Ali Baba and the Forty Thieves (1944) is more Robin Hood than One Thousand and One Nights. Like Arabian Nights, Universal took several creative liberties with the original story. “Ali Baba and the Forty Theives” is actually about a poor woodcutter who happens upon a magically closed den of thieves. The thieves are a band of cutthroats who keep their secret at any cost, but they’re all outsmarted by a clever slave girl named Morgiana. The movie does none of that since it’s another exotic tale starring Maria Montez and Jon Hall. Sadly, Sabu is left out since he was fighting in the war. Ali Baba and the Forty Theives begins with Ali as a child who pledges himself to Amara. In the book, Cassim is Ali Baba’s greedy brother.
In the movie, Frank Puglia plays Amara’s cowardly father Prince Cassim who betrays Ali’s royal father. Moroni Olsen briefly plays Caliph Hassan who is ambushed by invading Mongols who seize Bagdad. It puts the movie in a historical context since the siege actually happened with Kurt Katch playing the real life Mongol ruler Hulegu Khan. Ali survives the attack and happens upon the den of thieves. Like most adaptations, the den can only open with the magical word, “Open Sesame!” Ali helps himself to their treasure, but the thieves welcome him as one of their own. Fortunio Bonanova plays the kindhearted Old Baba who adopts him and gives him the name Ali Baba. Andy Devine plays the bumbling Abdullah who ends up being the kid’s nurse maid.
Ali Baba grows into a dashing rogue who leads his merry band of Forty Thieves to steal from the Mongols and give to the poor. Hall has his third on-screen collaboration with Montez as the lovely maiden Amara. Though their chemistry has gone away without a single kiss. Amara is forced to marry Khan by her father Cassim. Jamiel is a servant who helps Amara and wants to join the 40 thieves. Turhan Bey does a decent job, but the role was clearly meant for the fun-loving Sabu. Model Ramsay Ames plays a spy who gives Cassim information to tell Khan. The moment from the book where the thieves hide inside jars is reworked with them taking the Mongols by surprise. Ali Baba and the Forty Thieves is still a fun adventure despite copying a familiar swashbuckler.
