Continuity mistake: When the police find Nick, his body is half submerged in the water. When the cop points him out, he's on top of the rocks, not covered by any water at all.
Continuity mistake: At the end of the film, Victor tells Nick to write 'hey Annie' on plane's wing to send her a message. When Nick throws the plane and the camera shows it flying around, the words that Nick wrote are nowhere to be seen.
Nick Powell: I saw your face last night, Annie, and for a minute there I bet you would've traded places with me.
Principal Whitcliff: Anyone want to explain what happened?
Nick Powell: She, uh, finds me irresistible.
