Below the Belt (1971) is a pants boiler about boxing from schlockmeister Harry Novak with a double combination sure to leave viewers’ libidos TKO'd. The first hit comes from top-heavy Uschi Digard, followed by a body shot from arguably the first porno star, Rene Bond. Less notorious is Mirka Madnadraszky in her nude debut, which is sadly also her only exposure onscreen, but it's a full-frontal one. Another porn star, Terri Johnson, ensures this movie leaves you up for the count.
