Prisoner's Song (1930) ** 1/2 (out of 4)The Fleischer Studio produced a number of these animated short films where the "bouncing ball" would have audience members singing together. The story centers around four prisoners who are in the yard taking orders from their warden. We then get to the title song and the bouncing ball. For the most part this was a fairly entertaining short, although there's no question that these weren't meant to be anything overly special. They were cheap entertainment and for its seven-minute running time it's entertaining enough to watch. The animation was good and the song was decent.
