Continuity mistake: In the secret covenant, the amount of blood on Eve's white top decreases when Olivia the vampire doctor examines her wounds. This is most noticeable under the collar. (00:34:20)
Factual error: Detective Sebastian fires a total of 7 rounds at the Antigen van in the parking garage - three at the driver, two at the front-left tire, one right before the van nearly runs him over and then one after it passes him - without reloading, yet the Taurus Judge revolver he is using is designed to only hold 5 rounds in its cylinder. Later, after Sebastian has reloaded the revolver, he fires 8 rounds at Dr. Lane, again without reloading.
Trivia: Kate Beckinsale's stunt double Alicia Vela-Bailey makes a cameo during the opening sequence as a vampire escaping the purge. (00:03:40)
