All the Times MCU Stars Have Spoiled Their Own Films

When it comes to the Marvel Cinematic Universe, secrecy has proven to be vital throughout the years -- so much so that actors are normally terrified to confirm their involvement with a forthcoming project early on, fearful they may accidentally slip something significant ahead of the film's premiere. However, in recent years, it appears as though the Marvel snipers have become rather lax, as returning cast members have been noticeably captured accidentally letting details slip during interviews. With that in mind, we take a look at some of the biggest spoilers revealed by the Marvel cast themselves -- here's mainly looking at you, Mark Ruffalo and Tom Holland!

The Guardians Cast Spoilers Their Returns in Avengers 4:

It was always expected that the events of Avengers: Infinity War would be altered in one way or another, bringing back the characters we lost at the hands of the Mad Titan, Thanos. After all, with most of the Guardians gone, a third film seemed pretty pointless. Thankfully, the Guardians themselves had no problem confirming that they'd be back in May's Avengers 4, including Zoe Saldana's Gamora, who Thanos famously sacrificed in order to retrieve the soul stone, as well as Dave Bautista confirming a return as Drax. Were their comments a huge surprise? No. Unfortunately, though, in the case of Saldana, her comments came before Avengers: Infinity War officially hit theaters, meaning fans knew not to expect her death to stick, especially since she later went on to confirm she'd be back for Guardians of the Galaxy Vol. 3 -- which has since been put on indefinite hold.

Sebastian Stan on a Potential Avengers 4 Cameo:

Having made her debut in this year's Ant-Man and the Wasp, it seemed safe to presume Michelle Pfeiffer would be involved in the next Avengers film in one way or another. Of course, just because it was expected didn't mean it was confirmed. Until Stan opted to seemingly do so, of course. During an appearance at Ace Comic Con, Stan talked about a scene that they filmed which appears to be for Avengers 4. Despite doing his best not to say too much, the actor still managed to give away a tiny bit of news. "You look around and you just saw everyone from Samuel L. Jackson to Michael Douglas to Michelle Pfeiffer. Everybody was there."

Yes, both Michael Douglas and Michelle Pfeiffer will be back for Avengers 4.

When Tom Holland Accidentally Spoiled Peter's Infinity War Fate:

During the opening weekend for Avengers: Infinity War, which is easily the biggest Marvel Studios production to date, Marvel Studios president Kevin Feige decided to surprise some fans at a showing along with a few special guests. Not only did Feige bring along directors Joe and Anthony Russo, but he also brought out Spider-Man actor Tom Holland. As the crowd erupted in cheers taking in the actor's presence, Holland famously reached for a microphone and shouted "I'm alive!" to the crowd. The problem? They had yet to see the film and had no idea that Peter would turn to ash in Tony's arms at the end. A bit early there, Tom!

Thankfully, the crow appeared to take it all in jest and still went on to enjoy the film despite the actor's minor slip-up.

Star-Lord Apparently Manages to Meet Shuri:

Sometimes, spoilers come from the most surprising sources. In this case? It's none other than Shuri actress Letitia Wright. During an appearance at MCM London Comic Con earlier this year, Wright made a comment that seemed to suggest the duo would come to meet in Avengers 4. "Chris Pratt was genuinely a great person. He would like give me bible scriptures out of nowhere and then do a dance and leave. He’s great. I love Chris Pratt," she said.

Of course, as fans will note, the duo never crossed paths during Infinity War, and unlike Star-Lord, Shuri wasn't a victim of the snap. How the two will come together remains to be seen, as does how the film will go about reviving the killed-off heroes. However, one thing is for sure: Star-Lord more than likely has no idea what he's up against with Shuri.

Gwyneth Paltrow's Willingness to Spoil Avengers 4:

Pepper Potts & Tony Stark

Paltrow, who has been a part of the Marvel Cinematic Universe since the beginning, had been noticeably absent in recent films. That is, until she finally made a return in Spider-Man: Homecoming. Since then, Paltrow has been quite open regarding her return to the franchise, not only posting (non-spoiler) behind the scenes photos, but also posting straight up spoilers from set that seem to confirm she'll finally suit up in the fourth Avengers film. That isn't all, though. Paltrow has also previously teased a child for Tony and Pepper in the film, something that had been previously speculated following Avengers: Infinity War.
