Terminator, The Easter Egg - Sawed-Off Shotgun

In Terminator, Reese steals a shotgun from a police car (a little after he arrives in the past). He saws off the butt and hides it under his coat. This shotgun is the very same shotgun used in Aliens by Michael Biehn's character, Hicks, after the marines are told not to use their pulse rifles. Both Reese and Hicks are played by Michael Biehn and both films are directed by James Cameron.
