M1921AC Thompson is an American submachine gun first invented by John T. Thompson in 1918 during World War I that became infamous during the Prohibition era, being a signature weapon of various organized crime syndicates in the United States.

History[]

A thug is seen foiled by the Comedian in the opening credits while firing an Colt M1921AC Thompson into the air.

Trivia[]

  • In the special features the gun is revealed to be a specially built prop (likely a battery operated airsoft gun) that cycles the bolt slowly so the shot could be achieved. A rod was attached to the barrel to keep it level, as the weight would surely make holding it at such an angle one-handed difficult. Another thing wrong with this scene, if you watch closely you can see a casing eject from the Tommy gun several times even though the bolt hasn't even made one complete cycle (and subsequently only one casing should come out, not two or three).
