The Diamond Arm (Russian: Бриллиантовая рука Brilliantovaya ruka) is a Soviet crime comedy film made by Mosfilm and first released in 1969.

The film was directed by director Leonid Gaidai and starred several famous Soviet actors, including Yuri Nikulin, Andrei Mironov, Anatoli Papanov, Nonna Mordyukova and Svetlana Svetlichnaya.

The plot of the film was based on a real-life news item about Swiss smugglers who tried to transport jewels in an orthopedic cast.

The boss of a black market ring (known only as "The Chief") wants to smuggle a batch of jewelry from a foreign state into the Soviet Union by hiding it inside the orthopedic cast of a courier.

Due to a mix-up, they mistake Kozodoyev's fellow passenger from the cruise ship, the "ordinary Soviet citizen" Semyon Gorbunkov (played by Nikulin) for the courier.

Gesha and Lyolik (another of Chief's henchmen, played by Papanov) attempt to lure Gorbunkov into situations where they can quietly, without a wetwork, remove the cast and reclaim the contraband jewels.

American cars can be spotted in the Oriental city street scenes (which were actually shot in Baku, Azerbaijan, USSR): a 1954 Chevrolet 210, a 1955 Buick and a 1951 Oldsmobile Super 88.

This would have been an extremely rare sighting because the United States had sanctions on the USSR and did not sell cars within the Eastern Bloc.

It tells the story of a group of personified hares harvesting a mythological tryn herb (in Russian: tryn-trava) at night and proclaiming that they are not afraid of any predators, be they wolves or owls.

The tango-styled parodic song is about love and passion, and is played in the background during a scene when a femme fatale hired by the Chief's henchmen attempts to seduce and drug Gorbunkov.
