Banking on his renewed "leading man" status vis-a-vis Enter the Dragon, John Saxon plays J. B. Johnson in Moonshine County Express. The villain is racketeer Starkey (William Conrad), who has bumped off likeable moonshiner Pap Hammer (Fred Foresman). Now Starkey must do away with Hammer's toothsome daughters Dot, Betty and Sissy (Susan Howard, Claudia Jennings and Maureen McCormick). The girls receive unexpected help from Starkey's flunkey J.B. Moonshine County Express represents perhaps the best screen work of the late Playboy model Claudia Jennings, who evinces an intuitive acting ability.
