When you're doing an out-and-out comedy, the notion of preparing for a character - I hope I don't reveal too much of myself here - but, uh, no, I'm not doing anything.
James Caan told me at the end of filming 'Elf' that he had been waiting through the whole film for me to be funny - and I never was.
I know the nature of comedy, and you never know what will happen with the next movie or whether people will find it funny.
