Beast from 20,000 Fathoms, The
The Beast from 20,000 Fathoms is a 1953 B&W science fiction monster movie directed by Eugène Lourié and starring Paul Hubschmid (credited as Paul Christian), Paula Raymond and Kenneth Tobey. The screenplay is based on specifically the Ray Bradbury short story "The Fog Horn" and its stop motion effects were done by the legendary Ray Harryhausen. The movie depicts a fictional dinosaur, the "Rhedosaurus", which is released from its hibernating state in the Arctic by an atomic bomb test. The film is often credited with serving as the inspiration for the entire sub-genre of "prehistoric monsters on the loose" films, including Godzilla, which became popular during the early years of the Cold War era. Eugène Lourié, who directed this film, later directed the very similar film The Giant Behemoth in 1959, as well as Gorgo.
The following weapons were used in the film The Beast from 20,000 Fathoms:
Smith & Wesson Model 10
In the opening scene in the Arctic, Tom Nesbitt (Paul Hubschmid) and George Ritchie (Ross Elliott) use Smith & Wesson Model 10 revolvers for signalling. A S&W Model 10 is also seen in hands of an NYPD officer in his brave but fruitless attempt to stop the Rhedosaurus.
Most NYPD officers use Winchester M1897 shotguns against the monster.
Most National Guard soldiers and some NYPD officers are armed with M1 Garand rifles.
Some National Guardsmen are armed with M1903 Springfield (likely M1903A3) rifles.
Winchester Model 1892
A rifle that resembles Winchester Model 1892 is seen in hands of a police officer.
What appear to be Browning M1919A4 machine guns are mounted on National Guard jeeps.
Oerlikon 20mm Cannon
The Oerlikon 20mm Cannon on naval mounting is deployed against the monster.
M8 Rifle Grenade Launcher
In the final scene Corporal Jason Stone (Lee Van Cleef) uses the M1 Carbine, fitted with M8 Rifle Grenade Launcher to fire a rifle grenade, loaded with a radioactive isotope, at the monster. The grenade itself appears to be a movie prop, based on M9A1 Rifle Grenade.
National Guard troops use M9 Bazooka rocket launchers against the monster.
