Dom DeLuise, who spiced up such movies as "Blazing Saddles," "Silent Movie" and "The Cannonball Run" with his manic delivery and roly-poly persona, has died, his son’s publicist told CNN. Publicist Jay Schwartz did not disclose the cause of death, but DeLuise, 75, had been battling cancer for more than a year. DeLuise was surrounded by family when he died in a Santa Monica, California, hospital Monday night, son Michael DeLuise told CNN affiliate KTLA-TV.
