1 continuity mistake - chronological order
Directed by: Matthias Hoene
Starring: Michelle Ryan, Ashley Thomas, Harry Treadaway, Jack Doolan, Rasmus Hardiker
Revealing mistake: When Ray reminisces about having fought the Germans in WW2, a flashback is shown with him fighting in a bunker. He is carrying a No.4 Lee-Enfield rifle which requires the bolt to be worked after every shot to reload. However, he is shown firing two shots in rapid succession without moving his hands at all, revealing the shots to just be flashes added after filming.
Eric: Those things are vampires! We need crucifixes, garlic, silver, holy water, and Christopher Lee.
Ray Macguire: No, you soppy tart, those things are fucking zombies.
