Corrected entry: Given they share showers, it seems hard to figure out how Angela/Peter could've avoided being seen nude by any of the girls.
Corrected entry: Given Angela's really Peter it's never revealed how he could mask his male voice. Unlikely his aunt could've taught him how to sound more feminine.
Correction: Just because something is "unlikely" doesn't mean it's a mistake. It's not outside of the realm of possibility, hence it's not a mistake. His (very crazy) aunt has been forcing him to look and act like a girl. She's probably just conditioned him to speak with a lighter, more feminine voice. It's not exactly hard to impersonate a softer female voice. (I have a friend who does it all the time as part of his drag act.) You also have to factor in that Angela/Peter is still a child, and children naturally have softer, higher-pitched voices anyways.
Corrected entry: The water skier in the introduction suddenly disappears, then reappears.

Corrected entry: When Eddie and the little kids go camping with their flashlights, the light reflection of the camera hits Eddie in the face.
Correction: Copied from IMDb.
Corrected entry: In the flashback with Angela's father in bed with another man, the two children are watching. The young actress looks into the camera.
Correction: The young actress was most likely looking at something in the camera's direction in the bedroom.(the camera is not supposed to be in the movie).
Corrected entry: When the lunch scene starts, look at the lower left corner of the screen. One boy, after taking a bite of his burger, stares right at the camera.
Correction: The boy is actually a girl with her hair braided back and is plausibly staring at something on the wall, out the window, at a friend, or off into space.
Corrected entry: At the end, when you first see Angela sitting and humming, a crewmember is visible on the other side of the bleachers.
Correction: It is not a crewmember who is visible here. If you look closely, you can see that this person is taking off his clothes. This person is the uncredited college student who appeared completely nude at the end as Angela, stripping off for his scene.
Corrected entry: Right when Angela's true self is revealed, he/she is shown holding a knife. Then it cuts to the counselors who discover her. When it cuts back to Angela, he/she is now holding a hatchet.
Correction: The movie has an entire scene explaining Angela showers when the other girls don't.
