Plot hole: When the TV News report about Bogomil's shooting, they say that he was leading the investigation into "the so-called Alphabet Crimes". However before he was shot, there was only one crime - the Adriano's robbery.
Character mistake: In the final scene of the film where Axel is leaving, and Taggart says "See you around." when Axel turns around to start driving he says "Be cool Rein..." He accidentally uses the surname of the actor, Judge Reinhold, who plays Billy Rosewood. However he cleverly tries to cover it up by trailing off his sentence as he knows he has made the mistake.
