Other mistake: Throughout the saga, blood has been shown as essential for vampire's healing factor, and Selene herself used her blood to heal people. Somehow, this time around neither her or her pal David think in any way of this basic fact, making a complicated trip to the vampire doctor necessary, who simply feeds the vampire kid some blood, the very first thing any vampire would do to regain strength.

1 other mistake
Directed by: Bjorn Stein, Mans Marlind
Starring: Kate Beckinsale, Michael Ealy, Stephen Rea, India Eisley
Continuity mistake: When Selene gets to the parking garage, she is wearing her skin tight outfit and is only armed with her guns. But from out of nowhere, she suddenly pulls out a grenade. Her outfit has no pockets and it was not attached/hanging from her outfit.
Selene: For 12 years, I was held captive by the humans. The world I once knew has changed. Vampires and Lycans are now the hunted.
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)
