Michael Balcon certainly pulled out all the stops for his production. Originally conceived by Oscar Ashe as a combination of Christmas pantomime and operetta, based on the success of KISMET, it had become the West End's biggest wartime hit, as soldiers on leave flocked to see it -- with the censors reading the mail to and from their girlfriends, I imagine some of them felt the closest they could come to discussing what their plans would be "Get some tickets for the show and a hotel room since it will be too late to return home after. Bert said he and his girl had a great time."
In any case, the show not only played for over 2,000 performances, it toured for decades. The movie had to compete with that, so director Walter Forde had enormous sets built. Cinematographer Mutz Greenbaum keeps his camera moving constantly, and a great cast, including George Robey as Ali Baba, Fritz Kortner, Anna May Wong, Francis L. Sullivan, and Frank Cochrane reprising his role of "the Cobbler" from the original stage show, keep things hopping.
There are lots of complaints about British musicals, but considering MGM was about to enter on a series of stolid and very successful operettas starring Jeanette MacDonald and Nelson Eddy the following year, this lively example of the genre is a lot of fun.
