The Identity of the Giant?

Does anyone know the identity of the very tall man who played Sid Silvers' "kid brother" in this film (the "kid brother" whom Frank Fay was entirely dismissive of until he stepped on-stage and proved to be something close to seven feet tall)? I have an interest in physical giants and especially those in show business (Max Palmer, Eddie Carmel, Jack Earle, Lock Martin, Ed Wolffe, etc.). I've surveyed the cast listing but failed to come up with a name which sounded familiar. Any ideas? Steve.
