Longtime actor Leslie Nielsen, starring in films such as Airplane! and the Naked Gun movies, has passed away at 84.

Nielsen’s career reaches back into the very early days of television and starred as the earnest starship captain in the 1956 sci-fi film, Forbidden Planet. The actor turned to more comedic performances in the 80’s and made a name for himself delivering classic lines like “I am serious, and don’t call me Shirley”.

Reports say that Nielsen died due to complications of pneumonia in a hospital in Florida, surrounded by friends and family. The great actor will be sorely missed.
