Robert Charles Kerman (born December 16, 1947), also known as R. Bolla, is an American actor. He grew up in a middle-class Italian neighborhood of Bensonhurst, Brooklyn. As R. Bolla, he appeared in well over 100 pornographic films, most famously Debbie Does Dallas (1978). One of the very few adult performers to have an appreciable Hollywood resume on his merits as an actor, following a fading out of the so-called Golden Age of Porn, he embarked on a wholly mainstream career; it started well, but his past came back to haunt him. Kerman has said that in retrospect he had 'missed the boat' by taking porn work.
