Robert Charles Kerman (born December 16, 1941), also known as R. Bolla, or Richard Bolla, is an American actor. As R. Bolla, he appeared in well over 100 pornographic films, most famously Debbie Does Dallas (1978). He also appeared in the sequel, Debbie Does Dallas II (1981), but in a different role, that of a trucker. Kerman's breakthrough into the mainstream came in 1979, when he featured alongside Alain Delon and Robert Wagner in The Concorde ... Airport '79, in the role of Dulles Controller. In the 1980s, he starred in several Italian horror films, including Ruggero Deodato's exploitation classic Cannibal Holocaust, and Umberto Lenzi's cannibal films Mangiati Vivi and Cannibal Ferox. But he remained active in pornography throughout the first half of the decade, with notable roles including Lawyer Quim in Liquid A$$ets (1982), and Fritz von Holenwohl in the Henri Pachard directed Public Affairs (1984). In 1985, Kerman broke into television, with his role as an Attorney in an episode of Hill Street Blues, and supporting roles in two episodes of Simon & Simon.
