Claimed that he was cast as "Slim" in the Broadway play version of John Steinbeck's "Of Mice and Men (1939)" by Steinbeck himself because he showed up to the audition in bluejeans and Steinbeck thought he looked the part. Steinbeck was sitting outside the stage door on a chair when he made the decision as Geer filed past him.

Geer was an early boyfriend of Harry Hay, the Los Angeles Communist and radical who founded America's first large-scale gay activist organization, the Mattachine Society.
Grandfather of Kelly Linville.
Had a degree in horticulture. Later became a vegetarian.
Had a most unusual hobby of raising all the plants mentioned in the works of Shakespeare.
