Romancing the Stone is a 1984 adventure film starring Kathleen Turner as Joan, a romance novelist who gets caught up in a real life South American adventure when she is forced to find a mysterious treasure in order to rescue her sister. During her quest, she is assisted by Jack Colton (Michael Douglas), a bird smuggler. The film was directed by Robert Zemeckis (Back to the Future) and the cast included Danny DeVito and Zack Norman. Douglas, Turner and DeVito would later reunite for the 1985 sequel The Jewel of the Nile.
The following weapons were used in the film Romancing the Stone:
Jack Colton (Michael Douglas) carries a left-handed Remington 870 Wingmaster shotgun with shortened barrel as his main firearm in the film. (Michael Douglas himself is not left-handed.) In the first scene featuring the shotgun he fires it nine times without reloading, even though the gun does not hold that many rounds.
Colonel Zolo recruit some members of the local Police Force and at least one use the FN FAL rifle.
Ruger Mini-14 GB
Several Ruger Mini-14s are used by Zolo's personnel and Ira's men. One of them is seen used by Jack Colton (Michael Douglas). These Mini-14s are 'GB' or 'Government Barrel' variants, featuring the distinctive barrel with flash-hider and bayonet lug also used on the selective-fire Ruger AC556.
Valmet M71S
The Valmet M71S rifle (standing in for a Kalashnikov Variant) is seen used by Zolo's Men & Ira's Men.
Winchester Model 1894 (probable)
Though very difficult to spot due to lack of screentime, one of Juans henchmen seem to carry the Winchester 1894.
Unknown Bolt-action rifle
One of Juan's henchmen carry an unknown bolt-action rifle with a bent bolt-handle. It might be a Mauser derivative.
Machine Guns
FN MAG 58
As Jack and Joan escape, Zolo's troops open fire with the FN MAG 58.
