The Faculty

In The Faculty Robert Rodriguez and Kevin Williamson effectively mix elements from such films as "Alien", "Invasion of the Body Snatchers" and Williamson's other teen horror movie.

The Faculty takes place in a highschool whose faculty is gradually taken over by an alien organism. From the teachers it is spreading to the students' bodies, but a few students realize that something is terribly wrong.

The story has some logical flaws, but it is certainly entertaining with that twinkle in the eye that also characterizes Williamson's "Scream" scripts.
