"... why he made the leap from movies to television"?!?
How about the leap from almost complete obscurity to television? Ignoring a couple of films that flopped in the early 1990s, you have to go back to 1989 and National Lampoon's Christmas Vacation to get to when he was really making any movie worth talking about.
As far as the lowest form of lowest form of television, I do agree with Gary Mitchell
about 'reality" TV being the lowest form of television..... unless you count Chase's late night talk show, which lasted only a few weeks until it spiraled in for a smoking crash landing.
This fellow is far too full of himself for his own good!
