Character mistake: Alicia sings the code to Crane and tells him he must remember it exactly the way she does it. He doesn't. He leaves out the extra "la la" before the last stanza. Astonishingly, Alicia says "perfect, now two of us know it." (00:01:05)
Continuity mistake: Nelson spins the roulette wheel. We see a close-up of the wheel slowing down. Cut back to a full shot, and now the wheel is spinning faster than ever, even though no one has touched it. (00:42:15)
Continuity mistake: Nelson takes the captured assassin's knife and says that Alicia was killed with one just like it. But he can't possibly know that. He never saw the body or the weapon. Only Crane was with Alicia when she was murdered, and Crane, still missing in action, hasn't been in contact with Nelson. (00:42:15)
