With both Caddyshack and Vacation, it's not like the subjects were serious enough that they engaged my interest for another round. I love the characters, and the actors were great, but I didn't see the need to make another Vacation movie.
You can take wonderfully talented actors, wonderfully talented writers and producers, and, uh, do a wonderful show!... but if it doesn't hit with the public in two minutes, it's bye-bye.
People get on a show and they fought tooth and nail. Almost 95% of the actors out there want to be on a television series. Then as soon as they get onto one, no, no, I want to be a movie star. This television series stuff, no, no no.
