Seven Days in May

Seven Days in May (1964).

Seven Days in May is a 1964 thriller/drama film adapted from the novel of the same name by Fletcher Knebel and Charles W. Bailey II. The film stars Kirk Douglas as USMC Colonel Martin "Jiggs" Casey, who uncovers a plot led by General James Mattoon Scott (Burt Lancaster) to overthrow the President of the United States (Fredric March). The film was directed by John Frankenheimer from a screenplay by Rod Serling, the creator of the television series The Twilight Zone.

The following weapons were used in the film Seven Days in May:

M1 Garand

When White House aide Paul Girard (Martin Balsam) goes to visit Admiral Barnswell at the US 6th Fleet in Gibraltar, he passes by a Marine guard with an M1 Garand rifle.

Girard passes by a Marine guard before boarding the USS Kitty Hawk, the supposed flagship of the 6th Fleet. In the novel which the movie is based on, the carrier was the USS Dwight D. Eisenhower, which would actually be commissioned in 1977.

M16/SP1

US Army soldiers at "Site Y" are armed with original-model M16 rifles, likely the earliest appearance of this weapon in any Hollywood film. Colonel William "Mutt" Henderson (Andrew Duggan) seizes an M16 from another soldier while helping Senator Raymond Clark (Edmond O'Brien) escape detention.

The original M16, the first version, firing in a 20-round magazine, adopted in large numbers by the US Air Force in Vietnam. This has the original 3-prong flash hider. It would later be replaced by the upgraded M16A1 - 5.56x45mm

A soldier disembarks from a tracked vehicle to confront Henderson and Clark.

The sergeant, M16 in hand, talks to Henderson. It is worth noting that even though the film was made before the widespread adoption of the M16 by the US Army, it is set in a hypothetical 1970 where it is assumed that the M16 is the standard military rifle.

As Henderson seizes the M16, the flat receiver can be clearly seen.

Browning M1919A4

Tracked vehicles patrolling "Site Y" are fitted with Browning M1919A4 machine guns. Colonel Henderson orders a soldier at gunpoint to unload the cartridge belt from his Browning M1919A4 while helping Clark escape.
