Gerrit Graham (born November 27, 1949) is an American actor and songwriter. He mostly appeared in cult films, in disparate comedic or serious roles, such as Used Cars, TerrorVision, National Lampoon’s Class Reunion, Greetings, Demon Seed, Philadelphia Experiment II, Ratboy and others. He is probably best remembered as Beef, the glamorous rockstar in Brian De Palma’s Phantom of the Paradise and Phil Simpson, the doubting and skeptical stereotypical foster father in Child’s Play 2. He has also appeared in two different roles on the Star Trek television series; as the Hunter of Tosk on Star Trek: Deep Space Nine, and as Q (adopting the name Quinn) in the Star Trek: Voyager episode “Death Wish.” He was also the voice of Franklin Sherman in the animated series The Critic.
Graham attended but did not graduate from Columbia University — class of 1970. He has written songs with Bob Weir of Ratdog.
