Revealing mistake: When Blade shoots Quinn with a silver like dart, Quinn gets thrown back, and the wall behind Quinn bends when he hits. Then Quinn (stunt double?) bounces off the wall instead of being stapled to it. (00:09:10)
Revealing mistake: When Karen and Whistler start to fire at Frost's men, after they discovered Blade's hideout, Whistler shoots a black guy who has a large bump under his shirt, quite obviously the squib. (01:11:00)
Revealing mistake: In the final fight scene, Blade is fighting a bunch of guys. Before the shot goes to Karen looking down at Blade, Blade kicks a guy away, you can see the stunt wire pulling him back. (01:43:05)
Revealing mistake: When Blade uses his booby-trapped sword to knock down the serum from the wall at the end of the movie, you can tell the zoom in of the shot was sped up, as the rotating-timer-thing is spinning quicker than normal, and the screen is vibrating quickly.
Revealing mistake: When Blade is fighting Frost's men near the end, Blade kicks an Asian man to the ground. When he hits the ground, you see he hits some sort of mat or pillow under the dirt.
Revealing mistake: When Blade is being put into the chamber so they can siphon his blood, there are straps for his neck and his wrists. He is placed into the chamber and his hands are placed in the wrist restraints, no one reaches for the neck restraint. In the next scene, the strap is around his neck.
Revealing mistake: When Traci Lords approaches Blade, he tries to shoot her with the shotgun only for it to click, empty. He then proceeds to impale her with the silver stakes mounted in the end of his gun. If you look closely (probably more noticeable in full screen), you can still see the tips on the end of his stakes when she hisses at him, meaning that they're not actually inside her, even though she disintegrates in the next shot as if they were.
Revealing mistake: When Quinn is pushing through the door after Blade has cut his arm off, the full length of the arm is visible as he pushes the door open. On the other side of the door, his arm is gone again.
Chosen answer: I have taken the Russian subtitles and machine translated them, then edited for clarity. Here they are with and compared to the hard subs from the theatrical release of the movie. Russian version is in brackets. Here is the full conversation... MOSCOW Woman: (A good show. I'm glad we went.) Vampire: (It went well, I thought?) Woman: (Yes, keep up the good work.) Vampire: (I will try.) Woman: It's cold. Where are we going? (I'm so cold. Where are we going?) Vampire: It's a surprise. Woman: Surprise? (Surprise? Really?) Man: (Yes.) Woman: I like surprises. (You know, I like surprises.) Vampire: Then you'll like this - (Then you'll like it very much.) Vampire: (You have such sweet skin!) Woman: (Peter, what are you doing? You're hurting me!) Vampire: (You will live forever.) Woman: (Don't touch me!) Blade: (Hey, good evening.) Blade: Catch you at a bad time - Blade: - Comrade? Vampire then growls until blade draws his sword and it cuts to credits.
