Reitman was a king of comedies from the late '70s to the early '90s. He's the guy who directed like half the movies that parents the world over still have on VHS in the back of the closet somewhere.
You've got to hand it to Reitman, though; a lot of those movies are worth blowing the dust off of and digging out the VCR. (Well, we guess you could just stream them, but then you wouldn't get the full retro experience.) With Ghostbusters probably being his crowning achievement, Reitman's other flicks include Stripes, Meatballs, Twins, Kindergarten Cop, and Ghostbusters II (of course).
Ghostbusters is proof positive that Reitman really had the comic touch. It's crazy how the movie still manages to be funny after all these years. This is no easy thing, for example... um. Dang—we were about to give you an example of an 80's comedy that's not funny anymore, but we can't remember one—which sort of proves our point. Reitman was the Right-man.
Reitman's take on Aykroyd and Ramis's masterpiece of a script feels just as sharp as ever, and the choice of letting Bill Murray fill out his character with improv still makes Peter Venkman one of the most loveable huckster heroes in film.
Oh, and Reitman's list of credits as a producer is actually way longer than his directing credits; some of his producing highlights include Disturbia, Up in the Air, Old School, Beethoven, and Animal House.
