Corrected entry: When Selene was painting on the wall of the prison, when she was a young child the painting was at her eye height. Now when she returns, the painting (although faded by time) is again at eye height but now she is an adult. The painting should be under the water, but would serve no purpose there since the audience could not see it.
Corrected entry: When Michael goes out for some food, when the guards start chasing him he jumps out onto a police car with two guards in it, the car's roof bends down with Michael's weight/impact, the shot follows Michael as he escapes, when in that same scene the camera turns back to the car the two guards get out and the roof is intact. (00:27:30)
Corrected entry: In the beginning of chapter 13 at Tanis' lair, Selene is walking around with a UV bullet Machine Gun. Michael asks "How does a vampire have lycon bodyguards?" Soon the shot then pans to Selene, where the UV machine gun disappears, and then answers the question by opening up a secret compartment, where all of the UV guns are and says, "Because he was trading with him.UV rounds.

Corrected entry: When Marcus is being shot by Selene with silver bullets during the truck chase, he heals pretty well, despite being half-Lycan. But when Michael has been shot with "normal" bullets by the police, Selene says he could die. Surely, being a hybrid as well he should heal quickly, like Marcus.
Corrected entry: When Selene and Michael have gone to Tanis' place of exile, they are riding in a flawless Range Rover type vehicle. Michael fights with a Lycan outside and the two smash up the vehicle's windows and windshield. Then, as Selene and Michael are leaving Tanis', we can see light reflect off of the vehicle's unbroken and obviously-still-there windows and windshield.
Corrected entry: Just after the truck chase with Markus, and the sunlight is creeping over the hills, Kate Beckinsale and Scott Speedman crash the truck through the wall of a garage. As the sun is still shining into the garage, which would kill Beckinsale's vampire, Speedman covers all the windows with black paint. When he is done, the garage goes completely black. Does no sunlight shine through the big hole they made in the wall when they crashed through the garage? Came from a cinema viewing.
Corrected entry: Why are the vampires slain by the original werewolf transformed into werewolves? It was made clear in the first movie that surviving both infections is what made Speedman's character special, that no one else could, so the vampires slain by the wolf should just have died.
Corrected entry: It was shown in the truck chase seen and when Marcus sat down on the chair while taunting the banished historical guy that he didn't weigh over a ton. If this was the case, how was Marcus able to pull down the helicopter without anchoring himself on the floor? Even with infinite strength, he would have simply pulled HIMSELF up towards the helicopter instead of dragging down the copter down towards him.
