David O. Russell is probably my favorite filmmaker. He's not only a great director, but he's also a great writer.

The one thing for sure is, I don't ever want to waste a movie. I don't ever want to waste effort.

I gotta say - if I clicked on a movie interview, and the first part was all about Walt Whitman, I'd love that article.

When you screen it the first couple times, you're just trying to get the movie to work, trying to get the story to flow, trying to find out where your areas are where you have enough breath to laugh a little bit. So you're doing that the first two or three screenings, and then finally, you dial the movie in and it's working, and at that point, it's 50/50 as far as what's funny and what's working. Sometimes you'll put something in and it will just die so hard that it'll almost kill the movie.

'Blazing Saddles' is one of the funniest movies ever made.

You have to be able to fail with the improv. You have to not care.

The easiest time to be funny is during a fairly serious situation. That way you can break the ice.
