The producers originally wanted an African-American actor to play Bobby. Cleavon Little was a finalist for the part. Jeff Conaway was originally considered to play John, but asked to audition for Bobby. Conaway was the only white actor who was considered for the role. Casting director Joel Thurm later said that he thought Cleavon would have been a better fit to play the character.
