LOS ANGELES, California (CNN) -- 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 said.

Dom DeLuise was best known for his roles in Mel Brooks films as well as films with his friend Burt Reynolds.
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.

DeLuise was most famous for his supporting roles in a number of Mel Brooks films, including 1974's "Saddles" -- in which he played a flamboyant musical director who led dancers in a number called "The French Mistake" -- and 1976's "Silent Movie," in which he played the assistant to Brooks' director Mel Funn. He was also in the Brooks-directed "The Twelve Chairs" (1970), "Spaceballs" (1987) and "Robin Hood: Men in Tights" (1993).
