I remember when first, Stripes, and then Animal House came out - which I was really proud of, even though it was kind of loose and quite raucous - there were imitative movies that were not quite as good.
Movies either work or they don't work and they're either funny or they're not and we work very hard. To achieve that kind of work is really kind of delicate stitching.
A good actor is someone who knows how to take the part and make it real and make it honest and be effective in it. If it's in a funny movie and, as long as they are cast in an appropriate way, humor will come from it.
When you have a performer as talented as Bill Murray or as Harold, that can write as well as they can perform, you can do a final draft on the set if you think of it that way.
The home viewing experience is slightly different and there's room for these kinds of extra excursions.
I always thought that Bill Murray was one of the great actors that I've worked with. And I've worked with all kinds of people who are known primarily for their dramatic work.
