Continuity mistake: In the scene in the store, the clock behind Jemma shows the time as 10:20. In the next shot only a few seconds later, the clock reads 10:35. (01:06:40)
Factual error: In the scene where Patrick meets with the shrink and reveals he's a genius, he multiplies 548 x 297, and comes up with the answer of 16,765. In actual fact, the answer is 16,756. (00:07:45)
