Who Killed Cock Robin? is a mini-operetta that delighted 1935 audiences. The Academy Award nominated short highlights several caricatures of popular movie stars (particularly “Jenny Wren” as Mae West) and a wall-to-wall Frank Churchill score featuring a hysterical libretto. Some of the characterizations and humor that were considered acceptable at he time are no longer appropriate today, and consequently it’s become more difficult to view this short. However, as an example of storytelling, music and animation style, Who Killed Cock Robin? is still a worthwhile view.
