Harold Ramis died today when he was only 69 years old.
That's the bad news.
The good news is that we don't have to suffer through another Ghostbusters movie.
RIP, Harold. I remember him from his SCTV days (he was a performer and writer for the first 3 seasons) and his comedy scripts. Check his writing credits on IMDB. He had a hand in many late seventies-early eighties comedies including Animal House, Meatballs, Stripes, Caddyshack and, as mentioned, Ghostbusters. Also acted in many of them. One clever guy.
(And I liked Ghostbusters I & II, though I've been rather skeptical about the efforts at reviving it)
