ROOM SERVICE... although...
...ANIMAL CRACKERS, their first movie, was an adaptation of a Broadway show. The Marx Brothers first became famous on Broadway, after all.
The brothers took a couple of their movies on the road and performed them AS stage shows in front of live audiences. They did this with A NIGHT AT THE OPERA and A DAY AT THE RACES; I'm not sure if there were any others. Certainly DUCK SOUP would have been difficult to do in front of an audience.
Groucho, when interviewed, said that they did this because they wanted to see which gags worked and which ones fell flat. They also TIMED gags by the live audience's response... meaning that if a line or a gag got a long laugh from an audience, they would make sure that they edited the film with plenty of reaction time so that the laughter didn't drown out or "step on" the next line.
I remember a story from a book called THE MARX BROTHERS SCRAPBOOK about how the Marx Brothers and their entourage used to have a tradition that they would give writers-cast-crew members an expensive bathrobe on their birthdays. When the brothers were doing ANIMAL CRACKERS on Broadway, there was a crew member whose birthday was coming up and he kept saying "I can't wait to get my bathrobe"... so the brothers decided that they'd string him along and not give it to him right away. His birthday came and went... no bathrobe. So... the next evening, during the show, in the scene where Captain Spaulding (Groucho) makes his entrance, with an entourage carrying his trunks etc, the actors set the trunk down on the stage, and when the applause died down, the trunk popped open and this crew member got out and looked at Groucho and said "Where in the hell's my bathrobe?" and walked offstage.
They gave him the robe the next day!
