Guardians of the Galaxy
Bradley Cooper may have voiced Rocket Raccoon in Marvel's Guardians of the Galaxy, but the man in the green unitard was none other than director James Gunn's brother, Sean Gunn. "Sean is able to physically do something most actors aren't able to do, which is waddle around on all fours," said James. "He's always been an incredibly limber guy that can do a lot of strange physical things. And the fact that he's able to waddle around on his legs all day long at the exact height of Rocket is quite a feat and quite, quite difficult."
Space Jam
1996's Space Jam was one of the first films to ever use digital technology like CGI. The live-action/animation hybrid was shot in a virtual studio; Michael Jordan filmed in a 360-degree green screen room with motion trackers, acting opposite green-suited NBA players and improv artists against a green screen.
