Factual error: When Jason pushes Julius overboard, he would have drowned within minutes. No one can stay underwater that long without drowning.
Continuity mistake: In the film Sean and Rennie are on board the Lazarus. Sean puts both of his hands into his jacket pocket to get Rennie's gift. He never hands it to her, but In the next shot she has it in her hands. (00:16:55)
Revealing mistake: When Jason throws Wayne into the electrical switchboard, Wayne's jeans catches fire before he even hits the board. (00:49:30)
