Continuity mistake: In the middle of the film when the Bloodpack gear up ready to go out and into the sewers to find the reapers. Blade and Nyssa are talking at a table, Whistler shouts "hey Blade, give me a hand". In this shot we see Nyssa looking at Blade, but in the following shot she is now looking down and away from Blade.

Continuity mistake: At the end of the film when Reinhardt and Whistler are in a room together, Reinhardt turns and looks at the monitors and mouths "what the f**k?" he turns his head to the side, yet in the following shot his body is side on, and he is looking right at Whistler ready for the punch.

Continuity mistake: When Blade is fighting the henchmen near the end, he lifts the last surviving one into the air and you can see Blade's hand through the henchman's throat and it is obviously a dummy. Then, when he falls backwards, his hand is not on his throat, it is on the henchman's shoulder.
Continuity mistake: In the opening scene, Novak is walking down a corridor with a woman, and when she says, "Where did you get that scar on your chin? " Novak puts his hand to his mouth to cover it when he coughs, but in the shot from the security camera and normal view his hand is not at his mouth. (00:01:25)The-Immortal
Continuity mistake: When Blade meets the Bloodpack for the first time, Reinhardt (Ron Perlman) tries to instigate him, and the rest of the Bloodpack draw their weapons on him. When Nyssa motions for them to put their weapons away, we see a shot of the entire group putting their weapons down. Snowman(Donnie Yen) had partially drawn his sword, and resheathes it. Immediately afterwards it shows him doing this again. (00:31:50)
Continuity mistake: Just before the blood pack enter the house of pain, Scud shows Blade the pneumatic wristblades but doesn't actually give them to Blade. Blade can only be seen wearing them when he uses them on Nomak, after which they are gone again. I know they were retractable, but if you look even when retracted they should still have been visible. (00:34:29)
Continuity mistake: In the House of Pain sequence, Chupa is firing his machine gun at a Reaper who is fleeing across a balcony. As the shot cuts between different angles, Chupa's over-the shoulder angle indicates the Reaper has run over fifty feet. However, the balcony view where the Reaper runs directly towards the camera is the same section of balcony multiple times. Two female extras cower in terror against the wall several times before finally being killed by stray bullets. (00:46:16)
Continuity mistake: When Whistler shoots the lawyer from under the floor, you can see that the bullets go in at a diagonal angle, (up and to the left), but Whistler is straight under him. Therefore, the bullets would have to go straight up through the lawyer. (01:31:00)
