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.
Continuity mistake: In one scene, Annie is in Nick's bedroom, looking through his mementos, when she gets surprised by Nick's mother. She immediately jumps up, grabs a pack from the floor at the foot of the bed (grey or light green), and runs out of the house. In the very next scene, she and Nick are running down a wooded hill...but the pack is nowhere in sight.MovieBuff1971
