Goofs

In the two scenes panning around the cabin filled with Angela's victims, 10 bodies are seen. Yet at this point, Angela has only killed 9 people--Phoebe, Jodi, Brooke, Mare, Anthony, Judd, Ally, Demi and Lea.

After Ally is dumped into the swimming pool by Rob, she climbs out and sits on the side (near Sean & Molly) with dripping wet hair, as expected. Her hair is suddenly dry a few seconds later when Sean and Molly leaves.

Ally walks over to her bed twice after Angela crashes the raid.

After the two boys dump the bucket of water over Angela, a white rope appears by the door in a close-up of her.

The moon is out of phase. First it is full, then only three quarters full, then full again, all within the space of a few days.

The Polaroid camera Emilio and Charlie use to take photos of the girls is either a Polaroid Zip or a Polaroid Electric Zip. The pictures which Angela takes from them are Polaroid type 600. Zip cameras do not use type 600 film, only 8 series films.

Emilio and Charlie take nude photos of the girls from outside their cabin, but when Angela looks at the pictures later in the film, the pictures have clearly been taken by someone inside the cabin.

Several "dead" bodies are seen moving, breathing or blinking their eyes.

The supposedly running chainsaw Angela uses is clearly switched off.

Molly stabs Angela in the leg, but there we can see there is no wound.

There is no blood on Angela's knife when she stabs a girl.

This film is set in summer, but all the trees have brown fall leaves.
