Cuba is a 1979 movie directed by Richard Lester and starring Sean Connery as a British mercenary Major Robert Dapes, an expert in counter-guerrilla warfare, who is hired by Cuban government to organise successful operations against Castro's guerrillas. In Habana Dapes meets his love of old days, Alexandra Lopez de Pulido (Brooke Adams) who is now married a wealthy playboy.
Note: the movie was filmed in Spain, which affected the choice of screen guns.
Some government troops officers and warrant officers, including a sergeant (Ram John Holder) who leads the patrol unit, carry Astra 400 pistols.
Beretta M1934
One of the rebel workers on Pulido tobacco factory is seen with a Beretta M1934. The pistol is also seen in hands of midget Jesus (David Rappaport).
Smith & Wesson New Model No.3
After Julio Mederos' (Danny De La Paz) M1911 jams, he takes a Smith & Wesson New Model No.3 from a fellow girl guerilla fighter. The revolver is possibly a Spanish manufactured version.
Submachine Guns
Erma EMP
Erma EMP SMGs are used by both government troops and guerillas. They are possibly Spanish manufactured Coruña M41/44 in 9x23mm Largo caliber. In one scene Maj. Dapes (Sean Connery) briefly holds an EMP, taken from a female guerilla fighter.
In one scene a guerrilla fighter fires a submachine gun that resembles the experimental Vollmer-Erma VMP 1930, but most likely appears to be an EMP with the barrel shroud removed.
Suomi KP/-31
A Suomi KP/-31 with stick magazine is used by numerous guerilla fighters.
Sten Mk II
Sten Mk II SMGs of British and Canadian versions are used by guerillas.
Guerilla fighters and government troops use submachine guns that resemble Thompson M1928A1s. See talk page for the discussion of these guns.
M1921/M1928-like version
Guerilla fighters also carry unknown SMGs that have Thompson-style foregrips, pistol grips and rear sight guards but differs in having large space between the trigger guard and magazine well. Such SMGs are seen in some other Spanish filmed movies, like From Hell to Victory. Their general view allows to guess that they are visually modified Labora Fontbernat M1938 SMGs. See talk page for further discussion of these guns.
Star Si35
What appears to be a Star Si35 is briefly seen on guerilla base.
Madsen M50
A Madsen M50 is seen in documentary footage when victorious Fidel Castro enters Habana.
What appear to be a CETME Rifle of unclear model is seen on a documentary footage that shows a Cadillac Gage Commando armored car.
Machine Guns
Browning M1919A4
Browning M1919A4 machine guns are mounted on jeeps and M10 tank destroyers of government troops. Larry Gutman (Jack Weston) fires an M1919A4, dismounted from M10.
Browning wz. 1928
A Browning wz. 1928 is used by a soldier in the opening scene. This Polish light machine gun appeared in Spain during the civil war. The screen gun appears to be an early model with removed flash hider.
A pair of XVII century-style Wheellock Muskets are used as decoration in Gen. Bello's apartments. They are most likely non-firing replicas.
Trivia
M10 Tank Destroyer
An M10 Tank Destroyer appears during the battle on gas station. Maj. Dapes captures it from government troops and mans 75mm gun while Larry Gutman performs the duties of driver.
Fake "Sherman Firefly Tank"
A pair of M4 Shermans participate in the battle on gas station. They appear to be fibreglass replicas, built on Landrover chasis (originally for A Bridge Too Far).
Cadillac Gage Commando
A Cadillac Gage Commando armored car is seen in documentary footage. It bears Spanish red-yellow-red military insignia and has nothing common with Cuba though in the movie it is presented as belonging to Gen. Batista troops.
Mountain Gun
Two cannons are mounted on a railroad flatcar. They appear to be Skoda 75mm mountain guns of WW1 pattern.
