When I was a teenager, the actors I was really into were Mickey Rourke and Sean Penn. I saw 'Rumble Fish' on my 16th birthday, and around the same time, it was 'Falcon and the Snowman' and 'Bad Boys' from Sean Penn.

I understand Sean Penn. He has every right to look for El Chapo.

Sean Penn, for his acting as well as his writing and directing. There are so many actors I respect, but his reach is so wide.

I think every actor, you can say, has at one point decided to slack, phone it in. But Sean Penn shows up every day and does his job, and the character's always different. Always. 'Carlito's Way,' 'I am Sam,' 'Sweet and Lowdown.'

Daniel Day-Lewis and Sean Penn to me are the two best actors of all time. I'm just glad to have the pleasure to be in an era that they're acting while I'm acting. They're probably the best actors in my mind.

De Niro was a hero of mine. And Sean Penn. But I've realized I can't operate at that level of intensity. That's okay for movies. On TV, when you live with horror day in and day out, you have to protect yourself.

People still remember Sean Penn as Spicoli from 'Fast Times At Ridgemont High,' and if I can have, like, one-10th of his career, then I'm fine.

For me, one of my favorites, director-wise, is Tim Burton. I also really admire the work of actors like Sean Penn. He is probably my favorite actor because of his dedication and commitment to roles, and the ability to morph and change himself when he needs to. It's about dedication and commitment and a passion.

I want to be host of 'SNL.' I want to work with Steven Spielberg, Leonardo DiCaprio, J.J. Abrams, Emma Stone and Tim Burton, Sean Penn, Cameron Crowe. I want to work with Adam Sandler - he is so funny - and Tina Fey and Amy Poehler.

With Sean Penn, he wants to be surprised. He doesn't necessarily want what he's written, although we'll do what he's written. He likes the danger of acting.
