Heckler & Koch HK45 screen used by Denzel Washington in The Book of Eli (2010)
Even though the pistol had only been out a year when the film was made, a brand new HK45 was sanded and worn down to look very old (as the film takes place in a post apocalyptic 2043). The actual pistol is currently on display at the National Firearms Museum located at the NRA headquarters in Fairfax, Virginia.
