Is The Untitled Deadpool Sequel really untitled if it's called The Untitled Deadpool Sequel? These are the questions that keep us up at night. But what keeps the various cast members of the perpetually untitled film and its mega-popular predecessor up at night is the memory of some of their less successful films. It's a fact of the matter that you have to take on a few roles from time to time that you're not necessarily proud of, especially when you're just starting out. The cast of a movie like Deadpool had to pay their dues to get a spot at the table, so to speak, and the result is some surprising film roles throughout the years that you may have forgotten (or want to forget).

Taking into account things like Metacritic scores, reviews and box offices, we've combed through 15 actors who appeared (or are appearing) in the Deadpool movies to highlight some of these films that actors don't necessarily want you to remember. There's no shame in taking work, there are just some titles you don't want to be asked about on Access Hollywood, though everyone on this list has ultimately bounced back into bigger and better films. Here are 15 embarrassing roles of the Deadpool cast.

15 SERVING SARA (TERRY CREWS)

We don't know who Terry Crews is playing in the Deadpool sequel yet (speculation points to longtime S.H.I.E.L.D. agent G.W. Bridge) but he's quickly become a talking point after managing to keep his appearance in the film under wraps until he turned up in a trailer. Crews, a long time fan favorite thanks to roles on Everybody Loves Chris and Brooklyn-99, is also a comic book fan who was a long-time front-runner for Luke Cage.

But Crews, around in Hollywood since 1999, would probably prefer if you forgot his turn in 2002's Serving Sara. A vehicle for Friends actor Matthew Perry, Crews turned up as a bodyguard for the film's antagonist. Decked out in a long duster and black cowboy hat, Crews brought his A-game to the film, but it wasn't enough to earn the film more than a 4% on Rotten Tomatoes.

14 ROUGH NIGHT (KARAN SONI)

As the goofy and upbeat cab driver Dopinder, Karan Soni's career is off to a great start. The 29-year-old Indian actor has only been in Hollywood since 2010, but he's already generated a hell of a career, with appearances on the Amazon original series Betas and turns in Goosebumps and 2016's Ghostbusters remake.

But he did also have a small part in 2017's Rough Night. The Scarlett Johansson/Kate McKinnon vehicle was meant to be a massive comedy, but unfortunately, it failed to make waves at the box office. Many reviews found the film's leads to be funny and enjoyable but called the jokes scattered. It didn't help that it released a month before the similarly themed and much better received Girls Trip, drawing a number of unflattering comparisons.

13 EXTRACTION (GINA CARANO)

Following a successful career in Strikeforce, Gina Carano was ready for a career in Hollywood. Turning up in a solo feature, Haywire and making an appearance in 2013's Fast & Furious 6, it certainly looked like she was going to make it big as an action star. Her role as Angel Dust in Deadpool scored her some attention, but she's mainly worked on direct-to-video films.

One such film is a surprise to find in the dreaded direct-to-video market. Extraction from 2015  actually has a hell of a cast, with Bruce Willis and Kellan Lutz playing father and son CIA agents. However, Extraction has also proven to be one of Carano's worst-received films, with a pretty low 4.0 rating on IMDb and a Metacritic score of 25.

12 PUP STAR (HUGH SCOTT)

Hugh Scott's appearance in Deadpool as David Cunningham may have been something of a bit part, but it was memorable nonetheless. Directly tied to Wade's origin, Cunningham ultimately died in the same explosion that allowed Wade to escape. It's a blink and you'll miss it moment for many, but he plays a character that is memorable thanks to his humanity.

Scott's had a number of notable titles under his name, including a recurring role on The Fosters and an uncredited part in Suicide Squad. But he did also voice Westie in Pup Star, a role he may not want you to remember. A direct-to-video entry in the inexplicably long-running Air Bud franchise, Pup Star focused around a singing competition for dogs. Despite featuring such stellar characters as Simon Growl and Lady Paw Paw, the film still received lackluster reviews.

11 DUDLEY DO-RIGHT (JED REES)

Jud Rees is something of a "that guy" actor. That one guy you see in everything and say "Oh, it's that one guy." As the Recruiter who convinces Wade to attempt an experimental cancer treatment, Rees' Deadpool character was an understated evil, and as one of Wade's first victims when he finally becomes Deadpool, he's a very cathartic kill.

Rees has an interesting resume, including appearances in Galaxy Quest and Lake Placid. Low on the list might be his role in 1999's Dudley Do-Right film. Released to cash-in on the success of 1997's George of the Jungle feature, the Brendan Fraser vehicle saw Rees play a lackey to Alfred Molina's Snidely Whiplash. Unfortunately, Dudley Do-Right was a fraction of George of the Jungle's success and is considered a box office bomb.

10 PLANET OF THE APES '01 (ISAAC C SINGLETON JR.)

Getting nearly killed in the film's opening act, Isaac C Singleton Jr's Boothe is a fairly brief appearance. But Singleton has made a number of appearances in plenty of other films throughout the years, including Bo'sun in Pirates of the Caribbean: Curse of the Black Pearl and as The Vicar in Agents of S.H.I.E.L.D.'s fifth season.

Singleton seems to do his best work under heavy make-up, including a turn in 2001's Planet of the Apes reboot. The Tim Burton-directed reboot was meant to update and relaunch the franchise but ultimately was poorly received. The film turned a profit, but with heavy criticism and poor word of mouth, plans for a sequel were abandoned before they could really get underway. Luckily, the franchise was rebooted again with 2011's Rise of the Planet of the Apes.

9 VENDETTA (ROB HAYTER)

Stuntman Rob Hayter got the dubious honor of bringing the beloved Bob to the big screen. A long-time and often unwilling sidekick of Deadpool's, Hydra agent Bob amassed quite the fan following over the years, with his absence becoming more notable than Blind Al or Weasel's through Deadpool's comic history.

Blink and you'd miss Hayter's Bob, a small cameo that existed just to appease longtime fans. Hayter's no stranger to film though; he's made appearances as an actor as well as being a stuntman. With roles on Smallville and Arrow, he's definitely earned his stripes in comic book productions. But he may want you to forget his bit role in Vendetta, a 2015 WWE Studios productions starring Dean Cain and The Big Show. The film, which featured Hayter as a riot guard, was released to video on demand to middling reviews.

8 DAREDEVIL (STAN LEE)

Stan Lee's cameos have been some of the best aspects of Marvel films, but this practice is a lot older than most realize. Though his Oscar-worthy performance as the hot dog vendor on the beach in X-Men is one of the first ones many fans noticed, Stan's been making cameos in live action adaptations of Marvel properties as far back as 1989's Trial of the Incredible Hulk.

There probably aren't many of these roles that Stan would let you forget, given how much he seems to genuinely enjoy the cameos, but his turn in 2003's Daredevil must be up there. Appearing during the flashback origin segment of the film, a young Matt Murdock prevented a distracted Stan Lee from wandering blindly into traffic. Stan didn't reprise the role for Netflix's 2015 Daredevil remake, instead appearing in a photograph as a police officer.

7 THE EMOJI MOVIE (T.J. MILLER)

Though his appearance in the upcoming Untitled Deadpool Sequel has invited a bit of controversy, his casting as Weasel was praised by fans. A beloved character hailing from some of the earliest Deadpool stories, Weasel's role as Deadpool's lone friend and weapons dealer added some much-needed humanity to the book. Miller's Weasel was a relatively brief addition to the film but still managed to get a lot of play in the trailers.

Miller also had a highly publicized 2017 film with The Emoji Movie. Released at the height of the summer movie season, hopes were high that the film would cash in on the media sensation of emojis. Despite doing well at the box office, the film was universally panned as the worst animated movie ever produced.

6 SO UNDERCOVER (RANDAL REEDER)

Randal Reeder has done it all. Actor, producer, director, pro wrestler. He's really made a name for himself in Hollywood as a reliable hand, and that makes it a shame that he's not more well known. Reeder made a brief appearance as Buck, one of the bar patrons who Wade antagonizes early on in the film. Blink and you may miss him, but chances are you've seen his work before.

With work on King of the Hill, W. and 21 Jump Street, Reeder's got a great career. He also had a small role in the 2012 Miley Cyrus vehicle So Undercover. Having recently ended her run on Hannah Montana, So Undercover was one of Cyrus' first new projects. Reeder only had a small role in the film, but it's still one that sticks out like a sore thumb.

5 POOR PRETTY EDDIE (LESLIE UGGAMS)

Blind Al was always going to be tough to make work in a Deadpool movie. Portrayed in comics as Wade's hostage who was sort of a roommate that he genuinely cared about, the character became a fan-favorite despite Deadpool's cruelty toward her. For the film, veteran actress Leslie Uggams brought the character to life. Uggams, who returned to acting in 2009 after a lengthy hiatus, was perhaps best known for her roles in Roots and 1972's plane thriller Skyjacked.

Low on the list of Uggams' appearances, though, might be the 1975 horror film Poor Pretty Eddie, where Uggams' Liz winds up stranded in a hotel with a homicidal singer who fancies himself the next Elvis. With its dark tones and violent story, Poor Pretty Eddie exists today as a mostly forgotten relic, though it has received home video releases thanks to its status in the public domain.

4 SANDS OF OBLIVION (MORENA BACCARIN)

Morena Baccarin has had a long, healthy career with appearances on fan-favorites like Firefly. Getting cast in Deadpool makes her a rare instance of an actress on both sides of the comic book coin, having appeared on Gotham, as well as providing voice work for The Flash and Batman: Bad Blood.

But Baccarin's career also includes its share of spectacular duds, including the poorly rated telefilm Sands of Oblivion. Airing on the SyFy Channel in 2007 and featuring something of a Firefly reunion with co-star Adam Baldwin, this film centered around a cursed artifact from the set of The Ten Commandments appearing in the modern day. The film was poorly received even by SyFy movie standards, with a pretty pathetic 3.7 user rating on IMDb.

3 THE TRANSPORTER REFUELED (ED SKREIN)

Jason Statham's stint as Frank Martin generated a trilogy of enjoyable action romps, with The Transporter proving to be an exciting and well-received series of films. But when Statham chose not to return for a fourth film, the franchise was rebooted with The Transporter: Refueled, and Deadpool's Ed Skrein took on the role of Frank Martin Jr. in a middling plot that saw him racing to save his father, former Punisher actor Ray Stevenson.

The Transporter: Refueled received mixed reviews across the board. Sites like IGN praised Skrein's performance among the inevitable comparisons to previous entries, while Metacritic user ratings have the film hovering around a 32. Skrein managed to make a name for himself regardless, with roles in upcoming films like Tijuana Bible and Robert Rodriguez's Alita: Battle Angel.

2 THE MOD SQUAD (JOSH BROLIN)

With a storied career dating back to the ‘80s, Josh Brolin's role as Thanos gives him a film tenure on par with Robert Downey Jr., and his upcoming turn as Cable makes him uniquely an actor to exist on both sides of the Marvel Cinematic Universe now that Disney has purchased 20th Century Fox. But as with any actor with such a long career, not every film is great.

In 1999, with Hollywood starting to test the water with remakes, Brolin appeared as Billy, the former flame of Claire Danes' Julie in The Mod Squad. The film attempted to update the classic ‘70s television series for a big screen audience but failed to really light up the box office. Brolin has a lot of movies under his belt in his storied career, but he'd probably rather you forgot this stinker.

1 R.I.P.D. (RYAN REYNOLDS)

It was a long, strange road for Ryan Reynolds to reach the role of Wade Wilson. Obviously, you know of X-Men Origins: Wolverine, where he played Wade in the opening minutes and was replaced by Scott Adkins as Weapon XI for the film's finale. And you know about his follow-up to that, Green Lantern, alongside future Thor: Ragnarok director Taika Waititi. But there was one other comic book movie he appeared in prior to 2016's Deadpool.

Based on the Peter M. Lenkov comic Rest in Peace Department, the simply titled R.I.P.D. did have a bit of buzz surrounding it. Co-starring alongside fellow comic book movie stars Jeff Bridges and Kevin Bacon, the film, unfortunately, flopped pretty hard. Many critics saw it as a pastiche of Ghostbusters or Men in Black but saw it as lacking the same humor that made those films work.
