Early in his career, he was billed under the stage name of Gordon Addison because there was another Gordon Anderson in the
Actors’ Equity Association. Anderson made his
off-Broadway debut in the
Martinique Theatre production of
Until the Monkey Comes in 1966, garnering a
New York Drama Critics' Circle Award for Best Actor and receiving a
Theatre World Award nomination. The play ran for 76 performances. Decades later, one of his creations, a miniature set of characters from
Alice in Wonderland, was acquired by
Demi Moore. Anderson had voiceover roles in two of his wife's films,
A Reflection of Fear (1972) and
Ratboy (1986), voicing the titular character in the latter. According to his wife's autobiography,
Clint Eastwood offered Anderson the role of Leonard James in
Bronco Billy (1980), but at that point he had no interest in appearing in front of the camera.
Sam Bottoms, a substantially younger actor, was cast instead. Caritas Films, the production company Anderson and his wife formed following her disassociation from Eastwood, shut down in 2004 after failing to get any projects off the ground. ==Marriage to Locke==
