Avengers: Infinity War will see the Avengers' long-awaited team-up with the Guardians of the Galaxy as they take on the biggest baddie in the cosmos. But certain Marvel superheroes are staying grounded, in more ways than one.

"It's really nice to be here, for sure," Sebastian Stan said as he sat down with ET on the Atlanta, Georgia, set and took in his surroundings. "Especially on this spacecraft-- It's probably the only time I'll be on a spacecraft, to be honest. This is the Guardians of the Galaxy's, yeah? It's nice."

Both Stan's Bucky Barnes (formerly known as The Winter Soldier and now, as of Black Panther, White Wolf) and Anthony Mackie's Sam Wilson (aka Falcon), it seems, will remain Earth-bound for Infinity War, but Mackie also calls this movie "the most human" Avengers installment yet.

"It's a very, very interesting storyline that we've chosen to tell," he told ET's Brooke Anderson. "There are going to be a lot of shocking moments and the fans are going to get more than they expect out of this movie from all the characters. I think this is the most human of the Avengers movies, of all the Marvel movies. I think you'll be surprised to see how normal these superheroes can be."

Infinity War picks up after the events of Captain America: Civil War for both heroes, with Chris Evans telling ET that Falcon is part of Cap's Secret Avengers, functioning outside of government purview on counter-terrorism missions. Meanwhile, Bucky was cryogenically frozen in Wakanda until his HYDRA brainwashing could be undone.

"Friendships develop and they change," Stan said of the status of Bucky's relationship with Steve Rogers. "Sometimes you can know someone for, you know, 15, 20 years, but people change and sometimes they go in different paths. Those two guys have certainly known each other for a long time and they have a lot still in common and a bond, but now they've each had a lot of separate life experiences."

That's as much as he is willing to tease about Marvel's massive crossover event, out April 27, to avoid spoilers, sure, but also because he hasn't read a script. "Fortunately, there's a lot of kind people that point to where to look and who to follow," Stan said with a laugh. "I haven't met even half of the people in this cast yet. I've done the majority of my screen time with my friend, Anthony Mackie."

Mackie, likewise, is hesitant to name too many names of who's in the movie ("You have to realize which characters you're allowed to say and which characters you don't want to break the surprise on"), except for, of course, his buddy, Sebastian. To prove just how in-sync the two are, they each separately likened the bromance between their characters to the same 1982 comedy.

"Sebastian is a damn good actor and he's a damn good friend. It really is the three of us, he, Chris and I, our relationship works really well because there's a mutual respect," Mackie explained, pitching a spinoff for the two as, "Like Nick Nolte and Eddie Murphy in 48 Hrs. It would end up with us just beating the crap out of each other three or four times. I know it."

"To me, it's like Martin Brest's film classic, Midnight Run," Stan added. "It really is in my head like 48 Hrs. or a buddy comedy from the '80s or the '90s." Which is a spinoff we know many fans would pay to see. So, who do we get to cut the check? Stan smiled, "The right people to make that happen are certainly within feet from us right now. "
