Robert Kerman

Robert Charles Kerman (December 16, 1947 – December 27, 2018), also known as R. Bolla, was an American actor who had a pornographic acting career during what is considered to be the "golden age" period of the porn film industry during the mid-1970s to the early/mid-1980s. As R. Bolla (or Richard Bolla, a pun on slang terms for penis and testicles), he appeared in well over 100 pornographic films, most famously Debbie Does Dallas (1978). He was one of few adult performers to have an appreciable mainstream acting career, with a leading role as Professor Harold Monroe in the controversial horror film Cannibal Holocaust (1980).
