There are only three Harper children shown in this movie: Eunice, Philip, and Ellen. Yet, in previous "Family" sketches (the basis of this movie)and in the series "Mama's Family", there are three other sons, Vinton (played by Ken Berry, who plays Philip in this movie), Larry (played by Alan Alda) and Jack (played by Tommy Smothers). Brother Philip was played by Roddy McDowall in at least two of the original "Family" sketches.
