We played around and improvised a ton [in The Hangover], and I think it's hard to say at this point what's what. Gosh, I wouldn't even know how to take a stab at it. The script was so good that we really didn't need to improvise very much, but I think we just found a lot of moments on the set. It's really cool when you get onto the set of a movie and you start shooting the scenes and you start to actually incorporate the environment.

God bless him, I mean a lot of times you get non-actors on a set and they get really self-conscious, especially when doing something crazy like singing along with Phil Collins. They get sort of reserved and self-conscious. Mike [Tyson] completely trusted Todd [Phillips] and totally put everything into it.

I lived in New York for 10 years, I loved it, I never second-guessed it. There were definitely times when I thought, "I will never leave this place." And I kind of got into that center-of-the-universe mindset.

[Mike Tyson] was fantastic. Well, here's the cool thing about Tyson. It turns out he's a huge fan of Old School, which was one of Todd Phillips' earlier movies. So he got to the set and he already liked Todd and he trusted Todd.

I'm the worst in The Office. It's a problem. They've had to shut down the set for like 30 minutes because of me.

Sometimes you just create a joke out of thin air in the editing room. So I'm really glad I've had that experience. It gives me a little more confidence in front of the camera.

Don't be afraid of fear. Because it sharpens you, it challenges you, it makes you stronger; and when you run away from fear, you also run away from the opportunity to be your best possible self.
