This first film version of the Otto Harbach-William Collison stage farce Up in Mabel's Room was released in 1926, the same year that the original play premiered on Broadway. Newlywed Garry Ainsworth (played by the "original" Harrison Ford) discovers that his ex-wife Mabel (Marie Prevost) is in an adjoining honeymoon suite with her new husband Jimmy (Harry Myers). Before long, practically the entire male population -- and at least one female, Sylvia Wells (Phyllis Haver) is "up in Mabel's room." Not content with the slapstick hijinks inherent in the original play, the screenwriters contrive to include a wild nightclub sequence, replete with undulating chorus girls. Up in Mabel's Room was remade by Allan Dwan in 1945.
