With reference to the reviews below, I can guess how some Hitchcock TV episodes will turn out, too, but I wouldn't give the ideas and acting low points for that. (No more spoilers, please.)
I loved Jason Gray-Stanford in this--believably hurt, and then comical, giving a little insight into what the real actor is like. He probably does reasonably decent guitar and vocals when not on the set. But the episode's band and rock video were a riot!
And if you haven't seen "Marathon Man," by all means, rent or buy it--it's a classic--but don't watch it in a week you'll be seeing the dentist!
