Replacements - S1-E4

Other mistake: When Heffron is taking his throw at darts, he states that he needs a "double seven". When he takes the throw, the dart goes into the treble eight (an earlier close-up confirms that the board has the standard Gamlin configuration), yet, from the reaction he gets, he's made the throw he was going for.

Replacements - S1-E4
Continuity mistake: Just after the Sherman has knocked down the telephone pole we see two German guys up on a roof. In the long shot there is a bullet hole in the brickwork in front of them and in the close up it's gone. (00:34:30)
