Runaway is a 1984 science fiction thriller written and directed by Michael Crichton (the author of Jurassic Park). Set in the near future where robots are a part of everyday life, Tom Selleck stars as a Detroit police sergeant who is part of a special unit that handles robots that go against their programming and threaten the population. The film, which also stars Gene Simmons and Kirstie Alley, was a box office disappointment, but is notable for its predictions of how a police department would operate in the future.
The following weapons were used in the film Runaway:
Dr. Charles Luther's "smart" missile gun
The missile-firing pistol used by Dr. Charles Luther (Gene Simmons) in the movie was probably designed by the prop department. Though the model info is unknown, the base of the gun is clearly a 1911 style frame, probably provided by Detonics. Interestingly, the publicity materials for the film (especially in the theatrical poster) showed Tom Selleck holding the gun though he never uses it in the movie. The story alludes to one of the scientists working with Luther being an expert in propulsion & perhaps the supplier of the gun & its ammo. The runaway squad's chief tech officer (Stan Shaw) later calls the mini-rockets "smart bullets."
The projectiles are all electronic "heat seeking missiles" with a back half made up of solid propellant, making use of valves for directional control. They are able to be programmed to "go after" a specific person using a person's unique heat pattern as a signature.
Detonics 1911 Custom
The Detonics ScoreMaster is used as the service handgun of Sgt. Jack R. Ramsay (Tom Selleck) and Officer Karen Thompson (Cynthia Rhodes). The gun has the characteristic Detonics forward mounted rear sight, which was featured on the CombatMaster, but the longer grip frame of a ScoreMaster. It should also be noted that there is a line present on the slide where a combat master slide would end, the same gun can be seen in Terminator 2: Judgment Day used by Linda Hamilton. At the time the film was released, it was somewhat unusual to see uniformed law enforcement carry automatic pistols instead of the commonplace service revolver.
In the third act of the film, while trying to protect Jackie Rogers from Luther both officers use compact Detonics Combatmasters as sidearms.
Smith & Wesson Model 36
Johnson (Chris Mulkey) uses what is likely to be a Smith & Wesson Model 36 chief's special, but it is never shown well enough to be sure. Johnson uses it to fire at Ramsay after he kicks in the hotel room door, thinking it's Luther come to kill him.
Smith & Wesson Model 19
The 2.5"-barrel Smith & Wesson Model 19 is used by a robot (!)
In one of the films more tense scenes, Ramsay uses a laser gun with a battery pack on his belt to stop a murderous runaway inside a suburban home. It should be noted that Tom Selleck's character only fires this weapon in the film. He never fires his main sidearm, or his compact backup.
Custom Police Belt
Today it is very common to see officers carrying semi-automatic handguns, but in 1983 (when the film was shot) most police agencies issued revolvers. These custom belt rigs were way ahead of their time.
