Conversation so far:
What films did Marx Brothers make while at Paramount?
Their first two released films (after an unreleased short silent film titled Humor Risk) were adaptations of the Broadway shows The Cocoanuts (1929) and Animal Crackers (1930).

Question: Did they have any additional projects?
Self-contained rewrite: Did the Marx Brothers have any additional projects after The Cocoanuts and Animal Crackers?
