Seven Days in May is a 1964 thriller/drama film directed by John Frankenheimer and starring 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 (Frederic March).

M1 Garand

When White House aide Paul Girard (Martin Balsam) goes to visit Admiral Barnswell at the U.S 6th Fleet in Gibraltar, he passes by a Marine guard with a 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 on which the movie was based on, the carrier was the USS Dwight D. Eisenhower, which would actually be commissioned in 1977.

M16/SP1 Rifle

U.S Army soldiers at "Site Y" are armed with M16 rifles, which is likely the earliest appearance of the weapon in any Hollywood film. Colonel William 'Mutt' Henderson (Andrew Duggan) seizes a 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 U.S. 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 U.S 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 M1919 Machine Gun

Tracked vehicles patrolling "Site Y" are fitted with Browning M1919 machine guns. Colonel Henderson orders a soldier at gunpoint to unload the cartridge belt from his Browning M1919 while helping Clark to escape.

A variant of the Browning M1919 developed during World War 2, this model is designated the M37, with the ability to feed from either the left or the right of the weapon - 30-06. This example is shown without a tripod, only the pintle mount. This the MOST likely .30 cal machine gun to be seen firing from armored vehicles.
