Visible crew/equipment: Near the start when the vampire that's been burnt gets taken into hospital, watch the big glass cabinet as he gets wheeled in by 2 doctors - the crew and the boom mic are reflected in the glass. (00:10:59)
Visible crew/equipment: In the shot where Blade and Karen are running across the rooftop from the police firing at them from the hospital/morgue window, you can see the arms of a man holding a paintball gun on the right side of the screen. Paintball guns were used to fire projectiles that mimic the spark and smoke effects of bullet strikes. (00:15:35)
Visible crew/equipment: When Blade takes Karen to the hideout, Whistler injects her and tells Blade, "I give her 50/50 if she makes it through the night." In the shot where he says this, look directly behind Blade (near the ground, next to the drawers), and you can see a piece of equipment (it looks like extra lighting, but it's hard to tell) being moved out of shot by an out-of-sight crew member. (00:18:29)
Visible crew/equipment: There's a crew member or producer that is visible and is not part of the cast in the scene where Frost takes the pure blood to the beach to watch the pure blood burn. It is when they take the distance shot, and you could see Frost and his men around the pure blood kneeling on their knees. (01:03:36 - 01:04:48)
Visible crew/equipment: In the scene near the end of the film when Blade regenerates then kicks vampire butt you can see a man who looks somewhat out of place bouncing up and down in the background. (01:44:55)
Answer: I don't think it's so much a memory as it is Blade just equating Karen with his mother in that moment. The only way to convey his thought process to the audience, though, is to show his mother onscreen.
