Marvel Studios president Kevin Feige thinks it would be fun for Rocket Raccoon to meet Captain America.
With Marvel effortlessly connecting all of its superhero films in one cinematic universe, it's assumed that The Avengers will, at one point, meet with the Guardians of the Galaxy crew. But when will this happen (outside of fanfiction)? Marvel Studios president Kevin Fiege thinks it would be fun, but, in an interview with IGN, he isn't making any promises:
You know, the fun about The Avengers, as we we're gearing up to that, was how would Tony Stark deal with goody two-shoes Steve Rogers in World War II? What would Tony Stark think of a Norse god who wields a hammer? The brilliance of Joss [Whedon] was having fun with that. So who knows if and when these guys would ever connect, but it is fun thinking about, how would Steve Rogers react to Rocket? Or, you're right, Drax couldn't even have a conversation with Tony Stark! I have a theory that the more time Drax spends with Peter Quill, the more he's going to start to learn, perhaps, that people aren't always as literal as his species would assume.
Feige was also asked if supreme baddie Thanos (voiced by Josh Brolin) needs to demonstrate the full scope of his evilness and might, since it's presumed the Marvel films are building up to a big fight against its superheroes and the galactic tyrant.
I don't know. The truth is, anything I say would be a spoiler, frankly, on that. I don't think it's required. I think you could go right into a Thanos-centered movie and tell the audience anything you need to know. But the fun of our universe is that the characters can pop up in multiple franchises, so... perhaps.
What would you want to see if and when The Avengers meet the Guardians of the Galaxy? I admit, the prospect of seeing Rocket Raccoon exchange banter with Tony Stark would be a sight to see.
