20 Awesome Horror Movies With No Sequels

18. Slither

2006's barmy sci-fi horror-comedy Slither is the film that firmly put James Gunn on the map, and though initially unsuccessful at the box office, it enjoyed a major uptick in popularity once Gunn got his own mainstream breakout with Guardians of the Galaxy in 2014.

Slither remains beloved to this very day, with many wondering whether Gunn might now have enough clout to get the sequel made that was teased in the first film's post-credits scene.

But you certainly shouldn't count on it - in an interview last year Gunn revealed that he mentioned a potential Slither 2 to a producer shortly after the original's release, and the suggestion was basically laughed off.

Couple this with the fact that Gunn is now incredibly busy as the co-CEO of DC Studios and one of the more reliable blockbuster filmmakers working today, and it's tough to picture him ever going back to something as comparatively slight as Slither.
