Jim Cheng of USA Today has a lovely tribute to Harvey Korman of The Carol Burnett Show, who died yesterday at age 81. Korman’s best movie role was as the evil Hedley Lamarr in Blazing Saddles, one of four films he made for writer/director Mel Brooks. He was a nimble and versatile performer and an indispensable part of the finest ensemble ever put together for prime-time television. I especially loved him in the affectionate parodies of old Hollywood films. His Rhett Butler was a knock-out. But nothing he did made me laugh as hard as seeing him laugh at Tim Conway. He did his best to stay professional, but all Conway had to do was look at him and it was all over.
