A Japanese man claiming to be Mr Moto, of the International Police, is abducted and murdered soon after disembarking from a ship at Port Said in Egypt. The real Mr Moto is already in Port Said, investigating a conspiracy against the British and French governments. The dead man was his colleague, impersonating him to throw the conspirators off his scent. Mr Moto recognises one of the conspirators as a British Secret Service agent, and together they discover that the gang have mined the harbour in preparation for the arrival of the French fleet. Their aim is to throw the blame onto the British, which may start a second World War. Written by Daniel Frankham <>

Did You Know?


The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.

Warning: SPOILERS When Mr. Moto explodes the underwater mines ahead of the ships, the admiral is heard to say, "Turn left a hundred and eighty degrees." He should have given the command to veer to port. See more »


Admiral Lord Streetly: [First Lines] The two French squadrons are here now, Benthum, off Tunis. They plan to sail directly to Port Said and proceed through the canal and join our fleet for their maneuvers in the Red Sea.
Bentham: When exactly will they reach the canal?
Admiral Lord Streetly: We had a wire from the French Admiral this morning, says, "Fleet arrives Port Said, 23 o'clock, 16 instant, compliments, Delacour Admiral, Commanding."
Bentham: That's even less time than I thought. Isn't it possible to delay them somehow?

1939's "Mr. Moto's Last Warning" stars Peter Lorre as the Japanese detective, of whom nothing was heard once the Japanese bombed Pearl Harbor. Lorre is surrounded by a great cast, which includes Ricardo Cortez, Virginia Field, John Carradine, and George Sanders. Lorre not only plays Moto, but his cover, who runs an antique store.

The story concerns Moto's investigation of a conspiracy against the British and French governments. One of the "conspirators" is a British agent, and the two of them discover that the group has put mines in the harbor in order to blow up the French fleet -- the group had been desperately trying to find out the arrival date, and once they got it, set the bombs in place. Obviously, this is before Churchill blew the French fleet up in 1940 when the French refused to do so, which would thus give the Germans access to the fleet. The conspirators plan to blame the British for the bombing, hoping to start the Second World War.

Lorre does a great job, and Ricardo Cortez, as the head of the group whose works as a ventriloquist as his cover, makes an effective villain. Sanders uses a strange accent. Virginia Field, one of the "ice cream blondes" of that era was under contract to 20th Century Fox at the time; unfortunately, she never made it to the top, but she was in a lot of good films and is very pretty. John Carradine is in top form.

Entertaining as well as interesting, this is a good entry into the series featuring the brilliant and delightful "Mr. Moto."
