Real name, Bumgarner.
"During my trips to the Looney Left Coast in my quest for fame and fortune in Hollywood, I never met James Garner. I did audition for a small part in his film, A Man Called Sledge but did not get picked."
Neat. Looking on IMDB, all the minor roles appear to have went to Italians.
It has been so long, I cannot remember exactly just what part I read for but believe it (Mallory) went to Tony Young. He was not near as pretty as I was... so I guess I wasn't ugly enough again for a minor character!
Yeah, then Eye-Tallions got all the luck on that flick! Tony's real Italian name was... Vittorio R. Tomassi as I recall.
