Plot hole: Jack is observing Maldic, one of the hijackers, while he is checking in at a London hotel. Maldic receives a message, and after he has read it he throws it into a garbage bin. However, at this particular moment Jack is looking discreetly into the opposite direction and should have no reason to look for the message in the garbage bin later. (00:48:00)

Directed by: John Irvin
Starring: Forest Whitaker, Jeremy Irons, Jason Priestley, Briony Glassco
Revealing mistake: When Jack breaks into the Albert Dock Road building where the hijackers have their hideout, he enters through a wire-mesh-reinforced roof window. From below you see that he hits it once, causing a huge shower of big glass pieces (as if there were no wire mesh), and then the whole, almost intact pane comes down as if the mesh hadn't been connected to the frame.

Kate: These people are the dregs, Jack. Not even the governments can control them.
