The House That Shadows Built the Marx Brothers, with Davison Clark playing Mr. Lee, Theatrical Producer, which was intended to promote their forthcoming 1931 film "Monkey Business" (Clark later played the role of the frustrated Passport Official in "Monkey Business" and would also appear in the war scene in "Duck Soup"). The segment, containing material which was never included in any other Marx Brothers film, is a re-working of the first scene of their first successful Broadway revue "I'll Say She Is" (1924), which Groucho considered to have been the funniest work in the Brothers' career. Except for a few name changes and additional gags,
The Maltese Falcon (1931 film) in San Francisco. The film closely follows the plot of the book. The 1941 adaptation, which began with a revised version of the 1931 script, closely follows the book as well, although most references to homosexuality, stripping (the missing $1000) and other no longer permissible portions under the Motion Picture Production Code are missing. The dialogue for both films is often taken directly from the novel, verbatim. Differences between the two films are due almost wholly to Pre-Code aspects of the earlier film. In addition to an overall lighter tone and looser pace, the 1931 film contains sexually suggestive situations.
