The premiere of Avengers 4 is little more than five months away, and Marvel Studios has yet to release a trailer -- or even an official title -- for the hotly anticipated sequel. That's rumored to be part of a drastically different marketing strategy intended keep secret as many plot details as possible.

While studio President Kevin Feige has assured a trailer will indeed arrive before the end of the year, we have little idea when, precisely, that might be. The most recent rumor suggested Nov. 28, during a special screening of Avengers: Infinity War attended by directors Joe and Anthony Russo, but that obviously didn't pan out.

It remains a possibility that Marvel's marketing approach for Avengers 4 will be ... virtually non-existent. The sequel is likely going to shatter records with or without any major promotional campaign, due to the massive success of its predecessor and its jaw-dropping cliffhanger. That would be an effective way of bypassing the difficulties that come with releasing any footage from Avengers 4. The MCU has a relatively clustered 2019 calendar, with Captain Marvel hitting theaters in March, Avengers 4 in May, and Spider-Man: Far From Home in July. That tight schedule, coupled with Infinity War's ending, makes it virtually impossible for Marvel to market these movies in a traditional way. Any promotional material for Avengers 4 runs the risk of spoiling elements of Captain Marvel, and any for Spider-Man: Far From Home will most definitely divulge details about Avengers 4.

It's certainly possible for a limited-footage Avengers 4 teaser to be released while maintaining the secrecy surrounding the film. However, it would be nearly impossible to not give away anything of great importance in a full-length trailer. So, how exactly can Marvel effectively market Avengers 4? The answer is actually pretty simple: with Captain Marvel.

There are several reasons that Captain Marvel is the best marketing material Marvel has for Avengers 4, with Infinity War's end-credits sequence being the most notable. While Nick Fury had been a constant presence in the MCU until Avengers: Age of Ultron, he was nowhere to be found in Infinity War until the end-credits scene, in which he and Maria Hill fell victim to Thanos' finger-snap. However, this was not before Fury could fire a message off that's revealed to have been sent to Captain Marvel.

Set in 1995, Captain Marvel will introduce the strongest hero the MCU has ever seen with Brie Larson's Carol Danvers. The film will also tie in with Guardians of the Galaxy, with the return of Ronan the Accuser and Korath, while developing Captain Marvel's relationship with Fury, before he ever came across an alien or a superhero.

It's also a safe bet, given Marvel Studios' history, to assume Fury's last-second distress call from Infinity War will be included in a post-credits scene, although this time from Captain Marvel's perspective.

It was revealed earlier this month, in the Captain Marvel prelude comic, that Carol Danvers has always been Fury's plan B, even before the Avengers Initiative was formed: During the events of Captain America: Civil War, Maria Hill asks Fury whether he has a backup plan "in case the worst should ever come." He replies, "Nah. If we do our job right, we’ll never be in a position of having to call her."

To Fury, Captain Marvel was always a last resort, someone to be called in only if the Avengers failed to stop a threat to Earth. It's pretty easy to deduce, then, that the arrival of Captain Marvel will be the Avengers' best hope at defeating Thanos and reversing the events of Infinity War.

Furthermore, Marvel is planning to make Captain Marvel the new face of the MCU. It's in the studio's best interests, then, to ensure that any promotional material for Avengers 4 doesn't overshadow her movie. Avengers 4 represents the conclusion of the MCU as we know it, while Captain Marvel will serve as a springboard into the next phase, in which new and more diverse characters will be brought onto the big screen.

2018 was a banner year for Marvel Studios, which more than $4 billion worldwide across three films. Approximately 85 percent of that total came from Avengers: Infinity War ($2 billion) and Black Panther ($1.35 billion). The third film, Ant-Man and The Wasp, earned $622 million during its theatrical run, $216 million of which came from the domestic box office.

Similar to how Black Panther provided significant progress for black representation in superhero films, Captain Marvel will be a watershed moment for female-driven superhero films. It's imperative that Marvel markets Captain Marvel in a way that results in the film succeeding on a level much closer to that of Black Panther than of Ant-Man and The Wasp.

So, how exactly can Marvel Studios effectively market Avengers 4 through Captain Marvel? Simple: Limit the amount of Avengers 4 promotional material released ahead of Captain Marvel. With everything hinging on the arrival of Captain Marvel in Avengers 4, the most important thing Marvel Studios can do is make sure as many people as possible make the trek to their local multiplex for Captain Marvel prior to viewing Avengers 4.

And what better way to do an official title reveal for Avengers 4 than with a "Captain Marvel Will Return in [Insert Official Avengers 4 Title Here]" after the credits for Captain Marvel.

The untitled sequel to Avengers: Infinity War will release on May 3, 2019.
