Muscle Beach was shown in competition at Cannes in 1949 and won a prize at the Edinburgh International Film Festival in 1951. The short became a cult favorite, screening at film clubs around the world. Strick used an army surplus movie camera to shoot the film during weekends in the fall of 1948. The songs in “Muscle Beach,” composed and sung by political folk singer Earl Robinson, with lyrics by screenwriter and poet Edwin Rolfe, accent the film’s three-movement structure as it transitions between soaring gymnastics shows, flirty beachgoers and children playing near the now-demolished pier at Ocean Park.
