Comedian Gene Wilder was the star of such comedy classics as 'Young Frankenstein,' 'Blazing Saddles' and 'The Producers.'
A statement said wilder had been diagnosed three years ago but kept the condition private so as not to disappoint fans.
Wilder started his career on the stage but he's best known for his movies - especially his collaborations with Mel Brooks.
During the making of the generally forgettable 'hanky-panky' wilder fell in love with his co-star gilda radner, whom he married in 1984. After radner died of ovarian cancer in 1989, wilder spent much of his time promoting cancer research.
Wilder is survived by his wife karen, whom he married in 1991. Gene wilder was 83.
