There’s probably not a cinephile around the globe who doesn’t know Tony Stark, aka Iron Man. Robert Downey Jr. has played a lot of different roles, but he’s most well-known for Iron Man. He truly looks like he’s into wearing his armor, but he confides that even though he’s not usually claustrophobic, he cannot stand being in his costume for too long.

“I’m not claustrophobic, but after moving around in it for a couple of hours, your spirit is kind of broken and you’re like, ’Okay, time to bring in the stunt team.’” he says.
