Plot hole: The scene where the sisters are talking about killing the popular girl in class during P.E. during a game of Lacrosse, Bridgette is pushed into the body of a disemboweled dog. Everyone then starts to freak out seeing the dead animal. How could anyone, the students, teachers, grounds-keeper, not see that corpse until Bridgette was knocked into it?
Ginger Snaps (2000)
1 plot hole - chronological order
Directed by: John Fawcett
Starring: Mimi Rogers, Katharine Isabelle, Emily Perkins, Kris Lemche
Continuity mistake: Near the end Bridget blocks Ginger in the toilet by propping a plank of wood under the door handle so the door cannot open outward. Earlier, when Ginger was trying to cut off her tail, the door opened inward.
Trina Sinclair: Hey, why don't you get your slut-bitch sister a leash.
Trivia: Emily Perkins (Bridgette) had her hair shaved off shortly before the start of filming, so she had to wear an (occasionally obvious) wig during the shoot.
