Dom DeLuise, the comic/actor who was a staple of TV talk shows during the '60s, '70s and '80s, died last night in an L.A. hospital. He was 75. His humor made him a popular guest with Johnny Carson andDean Martin -- and it translated well to the big screen. Dom became a member of Mel Brooks' movie ensemble, co-starring in the comedies Blazing Saddles, Silent Movie, History of the World -- Part One and Robin Hood -- Men in Tights. He starred in Fatso, directed by Brooks' wife Anne Bancroft. And he did well as Burt Reynolds' sidekick in the Cannonball Run flicks and The End. He also poked fun at his weight by publishing several cookbooks.
