The man who starred in and/or wrote many of the funniest movies of the 80s and 90s has died:

"Ghostbusters" star Harold Ramis has died at 69 years old, United Talent Agency confirmed to ABC News today.

Ramis was known as much for his off-screen work — writing the "Ghostbusters" films, along with "Groundhog Day" and "Analyze This" — as he was for playing Dr. Egon Spengler in front of the camera.
