The Faculty (1998)

Continuity mistake: Mr. Furlong pushes Zeke into the fishing tank and it breaks, soaking him from head to toe with water. Moments later they are walking out and he is dry.

Coach Willis: You're not much into sports.
Casey: I don't think that a person should run unless he's being chased.
Coach Willis: "Being chased." I like that.

Trivia: The film's cover of "Another Brick in the Wall" (Parts 1 and 2) were performed by a band called "Class of '99." The band was a super-group made up of members from prominent 80's and 90's rock bands. (Including members of Alice in Chains, Rage Against the Machine, and Jane's Addiction.) The band was formed exclusively to record the covers for the soundtrack, and disbanded immediately after the film's release.

Question: In the scene where the main characters are talking about their peculiar behaviours i.e.- "Stokely, since when did you start liking boys" and "What, Delilah, you haven't gone without hairspray and contacts since birth". Can anyone please tell me what Delilah means when she says to Casey- "And Casey, since when did you become Sigourney Weaver?" I have never understood what it means but I think it might have some reference to the movie "Alien".
