In his 1989 autobiography "It Would Be So Nice If You Weren't Here...", Charles Grodin reveals that during a break between scenes, casting director Joyce Selznick took him to meet Roman Polanski for a part in Rosemary's Baby (1968). Grodin was wearing a cowboy outfit, sported large sideburns and had several bells hanging from his holster (representing the kills of his character "Bells Pickering"). Polanski had had drawings done to specify what each of the characters in his film should look like. But he still saw a similarity between Grodin and that of the young obstetrician and cast him on the spot.
