As Todd Mason noted when I posted stuff from Cocoanuts (1929), the Brothers made a silent short made way back in 1921. But Humor Risk (a send-up of a popular film of the time called Humoresque) was never released, and is now lost, so it don't really signify. You'll find a whole lot more talk about that film HERE. Anyway, due to the aforementioned, I ain't too uncomfortable calling Animal Crackers Marx Brothers #2.
