"You have to be really open to your acting partners and believe in the story." — Rachel McAdams

The physical part of comedy is as hard as a lot of action movies. It scares me, but in a way that I like.

Running through airports with pounds of luggage - that's a good workout.

A kiss with anyone, on or off camera, can be intimidating. I've been kissing for nearly two decades now, and I'm always convinced I'm not doing it right. Chemistry is so important in a great kiss. You can act your way through anything, but it's hard with a kiss.

During a movie, chemistry is so important, and yet they just assume actors can fake their way through it. That doesn't always work.
