If Penthouse Rhythm is paced more like a two-reel comedy than a mini-musical, it may be because the director was Mack Sennett alumnus Eddie Cline. Kirby Grant, Lois Collier, Judy Clark and Edward Norris play Dick, Linda, Patty and Junior, young members of a singing quartet. The kids have trouble getting their career started until given a boost by boxer-nightclub manager Maxie Rosenbloom (playing himself). Their success seems to hinge on a mere handful of songs, a fact that many genuine musicians found laughable. Halfway down the cast list as "Jank" is Jimmy Dodd, ten years away from his Mickey Mouse Club fame.
