Said in an interview that if he ever met the writers of "Mystery Science Theater 3000" (1988) he would "kick [their] asses" for their grilling of Mitchell (1975). This did not stop them from sending up another one of Baker's films, Final Justice (1985), in which they ridicule him even more. Baker later said the threat was a joke.
Studied at the Actors Studio in New York City following a stint in the army.
While Carroll O'Connor was recovering from bypass surgery, Baker appeared in O'Connor's place on "In the Heat of the Night" (1988) as Tom Dugan.
