F/X is a 1986 action thriller starring Bryan Brown as Roland "Rollie" Tyler, a movie special effects artist who is hired by the CIA to stage a phony hit. When the assassination appears to actually take place, Rollie finds himself using his expertise to evade the police and to prove his innocence. A sequel was released in 1991.
Roland "Rollie" Tyler (Bryan Brown) is seen firing a Smith & Wesson Model 28 loaded with special blanks when demonstrating how he will pull off the special effect hits.
McCarthy (Brian Dennehy) also is seen with what appears to be a nickel Smith & Wesson automatic. Though hard to tell, the weapon appears to have a large grip as well as the frame bulge, indicating a high-capacity S&W auto. The gun was previously listed as a Smith & Wesson 5904, which is not possible since the movie was released in 1986, while the 5904 and most other '3rd Generation' S&W autos were made in 1989 and later.
The assassin enters Rollie's apartment armed with a suppressed M1 Carbine manufactured by Plainfield. Rollie is later seen trying to use the rifle during a scuffle.
MP40
In the film's opening, a man in an overcoat opens fire in a restaurant with an MP40.
Uzi
A full size Uzi is seen used by the men guarding Nicholas DeFranco (Jerry Orbach) and Col. Mason (Mason Adams). Rollie, DeFranco, and then Col. Mason are seen using it as well.
