The hardest thing for me to do, and the best thing I've done and learned as an actor is to sacrifice being funny in certain circumstances in order to do something that makes sense for the story or the character, or emotionally.
Jonah HillWhen someone who is known as a comedic actor goes to drama, it often doesn't work out, because they really just chose wrong, I think - or maybe they're just not good actors. For me it's important making that transition seamless, and not a huge shock and jumping into cold water. It doesn't feel like I'm trying to shock you or anything. I'm just saying, "I'm a different actor than you thought I was. Don't put me in a box. I'm not just some kid running around screaming curse words." I have other tastes besides comedy. I love comedy, but I love dramatic movies just as much.
Jonah HillYou just have to be strong and don't be stupid; freedom of choice is a big responsibility.
