After the breakup of his first marriage and the dissolution of his business, Arbus moved to California in 1969 to pursue a new career in acting. His new career took off after he landed the lead role in
Robert Downey Sr.'s 1972
cult film, ''
Greaser's Palace'', in which he appears with
Robert Downey, Jr., who would go on to star as Diane Arbus's muse in
Fur. The 2006
Fur is a fictional account of the end of the Arbuses' marriage. Arbus also starred opposite
Bette Davis in
Scream, Pretty Peggy (1973), and was featured as
Gregory LaCava in
W.C. Fields and Me (1976). These roles led to his casting as Maj.
Sidney Freedman on
M*A*S*H. His work on
M*A*S*H helped his career as a character actor, and he eventually appeared in more than seventy TV shows and movies. He appeared briefly in the 1973 film
Cinderella Liberty as a drunken sailor; another 1973 film,
Coffy (starring
Pam Grier), featured Arbus as a drug dealer with strange sexual needs; in
Damien - Omen II (1978), he played Pasarian, one of Damien's many victims in
The Omen trilogy. In 1979, he portrayed a dance choreographer in
The Electric Horseman. Arbus is far better known for his television work, which includes over forty-five titles, with works as recent as
Curb Your Enthusiasm in 2000. Among Arbus's non-
M*A*S*H work for television are guest and recurring roles in such television series as
Law & Order,
In the Heat of the Night,
L.A. Law,
Matlock,
Starsky and Hutch, and
