Question: In Dracula (1992), in the scenes in the asylum where Renfield is being held, the guards can be seen wearing cages on their heads. Why? Was this a normal practice? I have heard of head cages for inmates but not guards. I'm not sure what the purpose would have been other than protection, but give the rest of their body is unprotected there has to be more to it. I've included the best image I could find. If I can get a better one I will update.

Answer: Why are the asylum guards wearing cages on their heads?


Question: In the initial timeline in 1997, Seaplane starts Jumanji and is sucked into the game. His parents supposedly donate the game to the city school, which is found again in 2017 by the new four players.  Upon beating the game, all five get back home: Seaplane in 1997 and the others in 2017.  What happens with the game module between 1997 and 2017 in this new timeline?  My best guess is that Seaplane needs somehow to restore the original events so that the four players join the game 20 years later, so that he can come back.  However who they are and how they joined the game is not mentioned in the movie, so how would he know where to put the module? It would also need to be found by exactly these four people being unexpectedly together at the same time (so 20 years later) without anyone grabbing the module before.

Answer:
What happens to the Jumanji game module?
