In the 1968 film The Splitstarring, among others Jim Brown, there were quite a few football scenes, among them Jack Snow catching a touchdown pass from Roman Gabriel. However, the movie announcer said it was "touchdown Frost" so we are to suppose it was Jack Snow playing Jack Frost.
In 1969 Snow played himself for real(?) in the TV Series Bewitched:
Inthe 1971 film Doctors' Wives he played and orderly but it was (uncredited) according toIMDB In 1978 he played "Cassidy" in Heaven Can Wait
