2. Justin Hammer
Iron Man 2
Sam Rockwell rules. Like, Ruuuuuuules. I'm so happy that he finally got his Oscar, because that dude brings it to everything he's in. And by "it", I mean some sweet dance moves.
He’s the strongest element in the MCU’s weakest entry, and he's the only villain in it that’s worth a damn. I mean, Whiplash? Really? For serious? He and his stupid bird are nowhere near interesting. But Hammer is an awesome and hilarious villain.
He's a tech company bro who really badly wants to be Tony Stark. But he isn't Tony Stark; he's a cheap imitation. His press conferences aren't as flashy, his jokes don't land, he has a really bad fake tan. He's just a try-hard with some knock-off drone robots to sell. He's literally Tony's greatest fear: being ripped off and sold to the war industry. It's incredible.
And Sam Rockwell sells his performance really well, which makes him the most memorable part of the movie. And in a bad movie, he's a real light in the darkness.
