Factual error: Edgar's license plate is "FROG BROS", but California only permitted up to seven digits at that time. It wasn't until 2014 when eight or nine digits were permitted, but even then only in "very rare cases." (00:27:40)
Continuity mistake: During the last scene, the strands of hair that Edgar has running down his face/right cheek are over the top of his head during some shots. Edgar is holding a book between both hands, so not moving the strands himself. (01:16:19 - 01:16:55)
Other mistake: Blake jumped through the window, shattering the glass and propelling many fragments through the air and towards/onto Edgar and Zoe, but no-one got cut. (00:34:10)
