I am trying to give the best performance possible in 400 pages. I want readers to be scared; I want them to be moved. Entertainment doesn't necessarily mean something trivial, but it does mean people wanting to get to the end of a book.

Having worked as both comedian and crime writer, the one thing I know is that both involve the delivery of a performance.

When I began to write, I was surprised at how little London had been used in crime fiction. Places such as Edinburgh or Oxford or L.A. seemed to have stronger identities.

I admire writers such as Elmore Leonard who can nail a character in three or four lines of dialogue, so he doesn't need pages of back story or clumsy exposition.

There's a great deal of echoing going on in 'Old School.' Mr. Piven, who played the upstart outsider in the 1994 campus comedy 'PCU,' has crossed over into playing the stiff martinet.

I love insane, stupid comedy, but I can only make it work if it's a character I can give some history to and make real. Like the guy I played in 'Little Miss Sunshine.' He's a maniac, but to me he was absolutely believable.

I think the world of comedy is a relatively small community, and especially for women in comedy, there just aren't that many people involved.

Comedy is very controlling - you are making people laugh.
