I like Al's character because it is hard to think of ANYONE in ANYTHING who was worse as an actor than him. His "acting" and the movie's utter stupidity make it funny.
Now go drink from the firehose.
UHF was an underrated comedy. I'd love to see Weird Al team up with the Zucker brothers (Airplane, Naked Gun) and do, well, about anything.
But, I still like Belushi. He understood what today's "comics" (Jack Black, Will Ferrell) don't get.... less is more. One raised eyebrow beats the hell out of overplaying a scene, every time.
Heck, the best laugh Jack Benny every got was from dead silence. ("your money or your life!!" ....................................................................................................................................................................)
