Visible crew/equipment: When the wolf begins to transform back to evil, as the wolf tries to take the wooden stake out of his heart, he leans forward and you can actually see the human arm behind him. He can't have an animals arm and a human arm at the same time - the arm is of an operator working the animatronic.
Visible crew/equipment: As Charley watches Billy dump a heavy black bag into the Jeep, the shot changes to a first-person view of Jerry walking on the roof getting ready to take flight as a vampire. As he jumps, a crew member and filming equipment are visible. (00:15:15)
Answer: Peter's odd behavior at Jerry's house made Jerry suspicious. When he discovers the shard of the mirror on the ground he finds out why Peter was spooked: Jerry doesn't cast a reflection. Jerry then decided that Charley's friends must be dealt with. In Ed, Jerry sees something which would lead him to believe Ed would make a good servant. Jerry turns Ed into a vampire and sets him against Peter while he himself deals with Charley and Amy.
