The loss of comedy legend Sid Caesar is being felt throughout Hollywood.
Caesar died at his home in the Los Angeles area after a brief illness, family spokesman Eddy Friedfeld said on Wednesday. He was 91.
The talented pioneer of TV comedy was infamous for his sketches with Imogene Coca that became classics and inspired a generation of famous writers. He also appeared in films like 1963's "It's a Mad, Mad, Mad, Mad World" and the 1978 classic musical, "Grease."
Cesar's influence is shown by the stars who are publicly mourning his loss:
"Sid Caesar set the template for everybody. He was without a doubt, inarguably, the greatest sketch comedian-monologist that television ever produced," Caesar's longtime collaborator and friend Carl Reiner on CBS Radio. "He could ad-lib, he could do anything that was necessary to make an audience laugh."
"He was a genius at everything," Larry King told CBS Radio.
Arnold Schwarzeneger, Whoopi Goldberg, Joan Rivers and film critic Richard Roeper took to Twitter to mourn:
