Visible crew/equipment: During the final battle, a vampire shoots into a totally dark room and kills a werewolf. He then lifts his gun and people are seen reflected in the sights.

Revealing: When Selene notices the sword laying on the rocks, the sword moves up about two inches between shots, you can judge it by looking closely at the handle of the sword.

Continuity: When Lucian stabs Selene from the top of the car, the depth of the stab to her shoulder and the amount of blood on the blade when Lucian retracts it are different.

Revealing: When Selene is firing her guns in the floor making a circle of holes so that the floor collapse, you can see in some shots the angle of her guns are pointing all kinds of directions. Instead of making a perfect circle the holes would be spread around the floor and the bottom of the walls in the hallway.

Revealing: After Selene bites Michael, Viktor picks him up and throws him through a wall. On the other side, he lands in a pool of water as do lumps of the wall, which float briefly before the shot ends.

Factual error: Every time the silver nitrate is shown on clothing, it is shown as silver. Silver nitrate in fact is black once exposed to light.

Continuity: When Selene breaks the glass and takes out the old book the amount of broken glass on the book differ between shots.

Continuity: When Selene slams on the brakes sending Lucian off the car, his arm blade disappears during his tumble, and reappears in the same shot once he stops. Viewed best in frame-by-frame.

Continuity: During the fight scene between the two Lycans, it shows a shot of Taylor (short Lycan) receiving a cut across the left side of his chest, but when it shows him in his human form it is on his right.

Revealing: If you go frame by frame in the scene where Selina cuts Viktor's head in half, you can see that the sword goes broad-side, past the front of his face, not making any cut through it.

Continuity: Selene is in Michael's apartment looking through photos, you can see the door to the apartment fully open in the background. When the phone rings, and we see Michael walking towards his apartment, the door is only partially open.

Audio problem: Near the beginning of the movie, while Selena is looking at the CCTV video from outside the subway station, Kraven enters the room and talks to her. Throughout their conversation, the sound quality of his voice changes as he walks away from where the mic is located (by Selena).

Visible crew/equipment: When Michael asks Selene who started the war she answers "They did. Or at least that's what we are led to believe". If you look really close on the side of the window you can see the shadow of the boom mike move.

Continuity: In the beginning when Rigel is about to jump off the balcony, some of his coat is hanging over the rail. When it cuts his coat is gone from the rail.

Continuity: When Selene discovers the blood on the wall in the subway chase the blood changes appearance between the shots.

Revealing: In the beginning when Selene chases the Lycan down the grate, she turns around and shoots him. Going frame by frame, you see that his squib (blood pack used to simulate being shot) goes off before she shoots.

Continuity: At the end when the 3 vampires are shooting at Michael, Selene drops behind them. The blood on the left side of her head disappears and reappears a couple of times. When she's taken them out it's back again. And it gets bigger and smaller all during the time it's there.

Continuity: When Selene runs up the stairs to release Michael from the chains, the door she left wide open is almost closed when the pursuers reach it.

Continuity: In the first scene when Rigel is crouching, taking pictures of the werewolves, he is holding the camera in his right hand just as he is about to jump down. However, when he is jumping, the camera angle changes and it can be seen that he is no longer holding a camera in his right hand.

Revealing: After Selene jumps off the building at the beginning and lands, there is a very large upwards pull (that stays in place until the camera cuts away) in her cape near her head that is in fact the drop wire running under her cape to the harness on her back (although the wire has been edited out).
