Factual error: When Van Helsing goes to Rome, the subtitle refers to the Vatican as "Vatican City". By the 1880's the Pope had lost all his temporal power, and his previous lands (The Papal States) were taken by the new Italy. The Vatican had no lands or authority over any of Italy or Rome. The Pope was a virtual prisoner inside the Vatican. Only with the Lateran treaty in 1929 (with Mussolini) did the Vatican gain independence as the "State of Vatican City".

Revealing: When Carl throws the new canister of arrows to Van Helsing during the vampire attack on the town, you can tell that when the camera cuts, Hugh Jackman just tossed the canister up in the air and grabbed it as it fell. The motion and angle at which is falls doesn't match up to the shot where Carl throws it.

Revealing: When the windmill starts to burn, we see a closeup of the Bible, before fire flares up in front of it. But if you look close, the angle of the fire is not correct in relation to the angle of the camera. Obviously the foreground fire was imposed over the scene later on.

Other: When Igor tortures the Werewolf behind the canvas, both of them can be seen as shadows, meaning a source of light is creating these images. When Igor hits the Werewolf with his staff, sparks can be seen through the canvas. First, as the image is a projection, the sparks would appear somewhere else on the canvas, and not exactly on the position of the staff's projected image. Even if the images are just silhouettes, the angle of the shot and the visible pillars indicate a much larger size then Igor really is. Second, such an intense source of light would alter the projection of the shadows a lot, not just a little bit in front of the Werewolf. In the case of silhouettes, they would completely disappear, as the source of light is between the 2 actors, and not at the side of them.

Continuity: As revealed in the DVD commentary, the character Anna's hair changes somewhat in some scenes. Noticeable is the very slight changes that occur before she finds out her brother is a werewolf. An original mistake was already corrected, but I assure you it's there. It's just hard to see.

Continuity: When Mr.Hyde strikes Van Helsing through the air, the hat falls off Mr. Hyde and you can see it fall behind him. When it cuts to Van Helsing flying through the air while shooting at Mr. Hyde, you can see the hat lies a few feet in front of Mr. Hyde.

Continuity: As the cage is being dragged up along the trees, right before Velkan jumps off, you can see ropes and equipment attached to the tree on the right. It cuts to Velkan jumping off the cage and the cage continues being dragged up along the tree. When the cage stops you can see the same ropes and equipment to the right as previously seen.

Visible crew/equipment: When Van Helsing and Anna swing up in the balcony with the rope and Van Helsing pushes Anna against the wall, you can see a shadow move away on Van Helsing's left side. They are supposed to be alone on the balcony and the shadow doesn't match their movements.

Continuity: When we get to Anna, right before she stabs Aleera, we can see traces of the concrete under the snow above her. Two shots later the snow is totally covering the concrete.

Continuity: After Aleera has grabbed Sara and Van Helsing runs after to the edge of the cliff looking for them, we see him holding his hand to his wound. When it cuts to Carl and the Frankenstein Monster getting to him we see him placing his hand on the wound again.

Revealing: When Dr. Frankenstein is holding the sword against Dracula, you can see its shadow on the wall to his left. However, when Dracula impales himself with the sword you can see the sword's shadow going through Dracula's shadow at the same time. Whatever the film makers have done, they have forgotten to remove the sword's shadow.

Revealing: When Verona grabs Van Helsing of off the chariot/coach, you can see the special effect of her claw holding Van Helsing is not quite matched up. The claw "wobbles" slightly over Van Helsing's arm. And this does NOT have to do with the fact he is struggling.

Continuity: When Van Helsing is talking with the undertaker and the undertaker says "Never to late digging graves", he lifts his shovel. When it cuts from behind him the shovel is lowered.

Continuity: When the Bride is down the well in the village, the sun is out. When it goes back behind a cloud, the shadow can be seen crossing the ground. When Carl points this out, the shadow is back where it was a few moments before.

Revealing: When it shows one of Dracula's brides drinking a glass of blood, close-up shots reveal it's actually tomato juice, shown by traces on the glass itself.

Audio problem: In the scene where the monster saves Anna by knocking down the last Bride, there is one shot where he turns to look at Anna framed in the window. His right leg support makes the hissing sound without any steam coming out of it.

Continuity: When Anna and Van Helsing are talking in the castle after the first vampire attack, the weapon Van Helsing is holding shifts from pointing over her shoulder to pointing across his face.

Continuity: After Van Helsing arrives at the castle for the first time, when Anna is rearming herself, her hands shift from on her hips to at her sides between a front shot and a rear shot.

Continuity: When the Frankenstein Monster manages to get himself loose from the table you can see him ripping off the strap by its attachment on the table. Later when Dracula gets to the table you can see the strap leather has been ripped in two on the middle instead.

Continuity: In the scene at the beginning of the movie where Dracula is at Dr. Frankenstein's castle, he says "over God." He then turns around with his arms at his sides and speaks to Dr. Frankenstein, with his arms remaining at his sides. When the shot changes to show Dracula's back and Dr. Frankenstein's front, we can see Dracula's fingers near his chest as if he pressed his hands together. There couldn't have been time between shots to change them from his sides to his front.
