I don't really do pranks any more. I have a laugh in the dressing room here, where it's safe, and the guys don't go to the papers and tell them what I've done.
I tend to get comfortable with the dialogue and find out who the person is in the script and try to hit that. People are sort of independent of their occupations and their pastimes. You don't play a politician or a fireman or a cowboy - you just play a person.
