The still-unidentified actor who played Sebastian Venable (seen only from behind) in Suddenly, Last Summer.
I'm guessing this is during the making of The Angry Hills and this is a local introducing Bob to the evils of drink...
I stand corrected. The last time I researched S,LS was some years ago, and the role was still not credited -- some people were even pushing the theory that Monty C. played the part!
