Later this year, Marvel will start production on Avengers: Infinity War Part I and Avengers: Infinity War Part II, with both movies shooting back to back over a massive shoot that is expected to last over nine months. While we know this superhero adventure will feature practically every established character in the Marvel Cinematic Universe, another key piece of the production team has been revealed. Composer Alan Silvestri recently confirmed that he has come aboard to provide the score for both Infinity War movies.

The news, courtesy of AlanSilvestri.com, shouldn't come as too much of a surprise, since Alan Silvestri provided the score for 2012's Marvel blockbuster The Avengers, which still stands as the studio's highest-grossing movie with $623.3 million domestic and $1.5 billion worldwide. The composer hasn't returned to the MCU since then, but he has been keeping plenty busy, composing scores for Flight, Red 2, The Croods, the TV series Cosmos: A Spacetime Odyssesy, Night at the Museum: Secret of the Tomb and last year's The Walk. He also composed the scores for upcoming movies Allied and The Croods 2.

Last week, a rumor surfaced that Avengers: Infinity War Part I would simply be re-titled Avengers 3, which came just weeks after directors Anthony Russo and Joe Russo confirmed that both movies will get new titles, but they hadn't figured them out yet. The filmmakers also teased that the Part I and Part II was misleading, since they aren't two halves to one big movie, but rather two separate movies, even though they will be shot back-to-back. Unfortunately, no plot details have surfaced yet, but there have been plenty of rumors bubbling as of late.

Writers Christopher Markus and Stephen McFeely confirmed last month that the Guardians of the Galaxy cast will appear in these movies, while directors Anthony Russo and Joe Russo let it slip that Captain Marvel will be included as well. We reported just last week that Brie Larson was the front runner for the Captain Marvel role, with her stand alone movie set to hit theaters on March 8, 2019. The directors have also teased that Infinity War will feature upwards of 67 characters, including all of the past and present Avengers, but they later backed away from that number.

Avengers: Infinity War will mark the culmination of the Marvel Cinematic Universe up to this point, with the heroes from the MCU squaring off against the Mad Titan Thanos (Josh Brolin), as he tries to amass all of the Infinity Stones and use his Infinity Gauntlet to rule the world. Every established character from the MCU is expected to join the fight, perhaps even the heroes from the TV side as well, such as Daredevil, Jessica Jones, Luke Cage, Iron Fist and the Agents of S.H.I.E.L.D., but they have yet to be confirmed.

Avengers: Infinity War Part I is slated to hit theaters May 4, 2018, followed by Avengers: Infinity War Part II on May 3, 2019. Marvel had previously slated Inhumans to be the last Phase 3 movie on July 12, 2019, but they have since removed it from the release schedule, possibly pushing it into Phase 4. We'll be sure to keep you posted with any updates regarding the Infinity War movies as soon as more details come in.
