Though each of the characters in Avengers: Infinity War will have their own arc, Thanos will be the true lead of the movie. A lot has happened since the Avengers first came together to stop Loki and the Chitauri, and Avengers 3 and 4 will tie together the MCU in what's sure to have been a daunting task for the minds behind the movies. But with so many characters, providing satisfying threads for everyone is no easy feat. It's because of this that someone who's been lurking on the sidelines in the MCU thus far will finally take center stage in next month's Avengers film: Thanos.

The Mad Titan hasn't had much to do in the Marvel Cinematic Universe to date, but it's clear that Avengers: Infinity War will truly be his film. Naturally, fans are excited to see unusual pairings and watch the Avengers and Guardians come together, but Thanos' mission to balance the universe by finding the Infinity Stones will help anchor everything else in the movie. It's why we'll be getting Thanos' origin in Infinity War, and that could provide Marvel Studios with their best MCU villain yet.

During Screen Rant's set visit for Avengers: Infinity War, we heard from stars Sebastian Stan (Bucky) and Anthony Mackie (Falcon) about just how much their characters and the rest of the heroes will get a chance to shine in the film. And though they're excited to see the different plots and tones of the MCU brought together, the actors make it clear that Infinity War is really the story of Thanos:

Sebastian Stan: I'm sure it's going to be challenging for sure because there's so many different tones to these films and that all of these characters carry. So I think it'll be interesting to see how tonally everybody fits into the same world. You've shot already some, right?

Anthony Mackie: Yeah. The great thing is that tonally, how the movie's working now everyone, it's not like you see one person who is the lead of the movie. It's truly and ensemble movie. I would say if anybody is the lead of the movie it's Thanos. And it's all of us working around, orbiting Thanos because he's such a big bad guy. He's the uber bad guy. He's the worst bad guy of all bad guys of all time. So you can't like put them in three scenes down, then a fight scene at the end. You really have to give them just due. So, our relationship and our scenes are more ensemble based. Everybody playing with a relationship with each other.

As the actors state, Thanos is a presence that can't simply fade into the background. Each character has had the chance to grow in various films, and Avengers: Infinity War will certainly continue that. But the movie will also be a chance to finally let the Mad Titan cut loose and make up for all the delegating and sitting around he's done so far. Still, Bucky and Falcon have their own journeys to go on over the course of the movie:

Sebastian Stan: It's certainly been a lot more of a stable situation for my guy, from what we've been used to and stuff. It's interesting, I'm really still discovering him. You can't just turn a hard right and everything's great. I'm still finding it to be honest.

Anthony Mackie: The thing for me is that continuous line, being a supporter of Cap and where he is in his journey. I kind of enjoy being along for the ride, step-by-step. You know when I first met the Avengers I was like, 'Holy shit. If the Avengers need me, I'm there!' You know it's just been ridiculous moment after ridiculous moment for me. So, you know when I walk up and see a talking raccoon, it's just a ridiculous moment leading to the next ridiculous thing. You know, so it's always just a fun journey.

During EW's Avengers: Infinity War coverage, we learned that Falcon isn't exactly pleased to be joining up with Team Iron Man after Captain America: Civil War. As for Bucky, he's been through a lot over the years and it's not clear exactly who he'll be when he heads back into battle. We saw brief glimpse of him after the credits of Black Panther and know Bucky will be the White Wolf going forward, but what state he's in after the Hydra brainwashing remains to be seen. Thankfully, Avengers: Infinity War will catch us up on Bucky, Falcon, and everyone else, while also providing a proper introduction to Thanos.
