Continuity mistake: Michell and the woman he meets in Uruguay are walking on the beach in the early morning. The sun behind them hasn't even come up over the horizon. There is one shot where it's much higher in the sky to the left of the characters. Then, it's below the horizon again.
Continuity mistake: Right at the beginning of the film, Michell walks into the gate of the school. The sun is off to one side and it's later in the day. Instantly, when he's inside the school, the sun is overhead.
