In the theater, you didn't have any marks. Your instincts in rehearsal told you what the blocking was. On film, they reversed it. They decided ahead of time what your instincts were, before you even arrived.
In the beginning, when you're acting in amateur theater and off-Broadway, it was unheard of that anyone else would get your costume. And it was important to get a good costume. You put time into that.
I hate to talk about typecasting, because being typecast as Columbo ain't cancer.
If I'm a guy reading a newspaper, and I hear this actor who I know gets great seats at basketball games, and he's complaining about being typecast, I think, 'Hey man, count your blessings.'
I've been asked a few thousand times how much of Columbo is Falk and vice versa.
When I go see a basketball game, I'm always in the front row. I always have a table at a restaurant; I never have trouble getting a taxi.
