The following weapons were used in the film Chapter 27:
Smith & Wesson Model 36
In the film, Mark David Chapman (Jared Leto) carries and uses a Smith & Wesson Model 36. The revolver that was used by Chapman to shoot John Lennon in real life was a Charter Arms Undercover, but the Smith & Wesson Model 36 bares a close resemblance to a Charter Arms, and was probably used due to its availability.
Smith & Wesson Model 36 - .38 Special
The actual Charter Arms Undercover revolver used by Chapman to assassinate Lennon - .38 Special
Chapman unfolds his revolver. Note the S&W-style cylinder latch with textured ridges rear of the screw, not forward as with a Charter Arms revolver.
Mark David Chapman (Jared Leto
) points his revolver at the wall, where on the other side are "two obvious homosexuals". This picture shows the ejector rod catch lug that the Smith & Wessons have, unlike older model Charter Arms Undercovers.
Chapman practices shooting John Lennon in front of his hotel room mirror. Once again, the ejector rod catch is clearly visible.
In the film, an actor named Mark Chapman (middle name not David) plays John Lennon.
