I can't remember the name of the movie (I believe it was Piper's big debut), it involved aliens taking over the Earth and Roddie finds some sunglasses in an alley that allow him to see aliens through their human disguises. I believe it was a Carpenter movie from the early nineties.
Who said it first, Piper in the movie, or Duke Nukem in a video game?
I know, who cares?
Edit: 1988. The Movie is "It Lives", directed by John Carpenter.
A "B Grade" movie, to be sure. But pretty entertaining none the less. Has anyone here other than myself seen it?
