Visible crew/equipment: In the scene where the souls are coming out of Freddy's chest, in the first close-up on the bottom left of the screen you can see a man's hand holding a black stick to manoeuvre the little arms. It's real fast but noticeable on standard play. (01:20:45)

Freddy Krueger: How's this for a wet dream?
Trivia: In the beginning of Nightmare on Elm Street 4: The Dream Master we learn Kincaid's dog is named Jason. Perhaps as a homage to the killer from Friday the 13th?
Question: Why does Freddy use Alice to gain access to new victims?
Answer: He'd killed her friends in the previous movie, remember? When he came back she'd had time to recover and make new friends.
That was Kristen, not Alice. Alice gives the answer to this question herself, while talking to Dan in the diner. She says that Kristen was the last of the children of the people who killed Freddy, and "maybe Freddy can't get to the new kids unless there's someone to bring them to him."
Answer: As Kristin was being burned to death in the boiler, she passed her ability to pull other people into her dreams to Alice. This enabled Freddy to get new victims.
