'Avengers: Infinity War' spoilers: Marvel exec hints at what could possibly go down in the massive film

Marvel is starting to lay the marketing foundations for their movie slate next year with the release of the "Guardians of the Galaxy Vol. 2" trailer as well as the first look at Tom Holland's incantation of the web-shooting hero in "Spider-Man: Homecoming." While these projects ae expected to take the front stage in the coming months, silent work on what could be the biggest Marvel Cinematic Universe (MCU) film thus far in "Avengers: Infinity War" has also begun.

In a Twitter post, courtesy of Marvel Co-President Louis D'Esposito, briefings are already being done for the cumulative event that will bring everyone to the MCU, even those who have yet to debut in a standalone like Captain Marvel (Brie Larson). It can be remembered that a couple of weeks ago, rumors had it that official production for the flick has already started; however, there were no official announcements from Marvel. This, however, solidifies the assumption that the project is already shaping up regardless of whether principal photography has already hit the ground or not.

The update was quite simple with the Marvel exec throwing a photo of the "Infinity Gauntlet" comic book series, which could mean that the third "Avengers" film might be a melding of both the "Gauntlet" and the "Infinity War" stories or a just a new spin of the former. Treading the main narrative of the "Gauntlet" source material only rounds up when Thanos erases half the sentient life, which could mean that "Avengers: Infinity War" could end with almost all of the superheroes banished. Still, it would be difficult to take the story page by page given that first, Marvel Studios does not have the rights to a lot of the key players in the story arc and two, the history is just too convoluted to cram into a two-hour film.

Nevertheless, the movie production company is known to be cherry-picking plot points across their massive story library and putting them together in a single film. Case in point is what took place in this year's "Captain America: Civil War." While the Steve Rogers' (Chris Evans) threequel took on the concept of the Cap fighting Iron Man (Robert Downey Jr.), it also tweaked some details offering a fresh take on a beloved comics run.

D'Esposito's message also coincides with that of the head honcho of the Marvel Studios, Kevin Feige who already spilled that they are "intercutting a lot of stories in that movie in a lot of different locales, as it sort of is in the Avengers movies as well; who is facing off against who. In this movie, it's going to be fun to mix that up."

"Avengers: Infinity War" will hit theaters on May 4, 2018, while its direct follow-up, the still untitled "Avengers 4" will debut on May 2019.
