In the scene where Starla is about to stab monster Grant, Grant rises to kiss her. In the shot he gets up, the head of the crew member that boosts him up is clearly visible.
Jack MacReady: Where is the Mr. Pibb? I told your secretary to pack Mr. Pibb. It's the only Coke I like. Goddamn Brenda exploding like a water balloon, worms driving my friends around like they're goddamn skin-cars, people are spitting acid at me, turning you into cottage cheese, and now there's no fucking goddamn Mr. Pibb?
No plans at the moment but if it did, it would most likely be direct-to-DVD.EDIT: Director Gunn has hinted his interest in a sequel, but he is not sure if he wants it to be his next project.
Q
Is this movie like Night of the Creeps?
A
To a certain degree, Yes. Night of the Creeps (1986) and Slither both feature alien brain slugs/parasites that enter humans through the mouth and turn their host into a killing zombie.
