1941 is the 1979 World War II comedy directed by Steven Spielberg that follows the chaos surrounding a possible Japanese invasion off the coast of Los Angeles in the days following Pearl Harbor. Loosely inspired by an actual event, the film features an all-star cast which includes John Belushi, Dan Aykroyd, Warren Oates, Ned Beatty, Tim Matheson, Slim Pickens, Toshirô Mifune, Christopher Lee, Treat Williams, and Jaws veterans Murray Hamilton and Lorraine Gary. The film received mixed reviews and its box office results did not meet studio expectations. In the years since it's release ,thanks to home video and heavy cable television play, the film has achieved a cult movie status.
The M1911A1 is carried by several characters in the film including Capt. "Wild Bill" Kelso (John Belushi), Col. "Madman" Maddox (Warren Oates) and Captain Loomis Birkhead (Tim Matheson).
The M1928A1 Thompson machine gun is used by US troops defending Los Angeles.
Rifles
Arisaka Type 38 rifle
Arisaka Type 38 rifles fitted with bayonets are seen in the hands of Japanese sailors that capture Hollis Wood (Slim Pickens).
Remington 700
A Remington 700 is used by Claude Crumn (Murray Hamilton) to take potshots at the Japanese sub from the ferris wheel. This was anachronistic for World War II, having been introduced in 1962.
Springfield M1903
U.S. soldiers are also armed with M1903 Springfield bolt-action rifles in the film.
The Browning M2 Aircraft heavy machine gun is seen used by US troops defending Los Angeles. These machine guns are also as well supposed to be the primary armament of Wild Bill's P-40, but when fired these appear to be mockups.
Browning M1917 machine gun
Sgt. Frank Tree (Dan Aykroyd) fires the Browning M1917 freehand and when mounted on his tank. Later, Wally Stephens (Bobby Di Cicco) is seen using the tank's machine gun. Other Browning M1917 machine guns are manned by soldiers opening fire on the planes flying over Los Angeles.
