Question: Evil tells of his assistants, "tell me about computers". And he later says, "show me subscriber trunk dialing". Why does such a powerful entity have an interest in technology? (01:30:45 - 01:31:35)
Answer: Remember his whole speech about technology being his version of the universe, while the Supreme Being concentrated on nature?
Question: Is it me, or does Medusa's head open her eyes as Perseus holds her head up after leaving the temple?
Answer: To me, it just looks like the way the prop catches the light as the actor lifts it up, and then higher up, the angle of the prop isn't catching the light in the same way.
Answer: I watched this scene several times on YouTube. When Perseus walks out with the severed head, the eyes are closed. Just as Perseus raises it, Medusa's eyes suddenly appear to open. Zeus is then heard telling Perseus to "fulfil his destiny" amid the thunder and lightning. Her eyes are wide open at this point. I interpreted this as showing that Medusa's power still resides within the head, even though she is dead.
Question: If the bear died in the fall, assuming the fall did kill it, then how did Tod survive?
Answer: Since we don't really know how he died, he could have drowned and not died on impact. Bear may not have been a strong swimmer or sustained too much injury from the gunshot to swim to the surface. However, in physics, force = mass * acceleration and thus larger creatures will hit the water with greater force than small creatures (as the old cliche goes; the bigger they are, the harder they fall). So it's possible for Bear to die on impact and not Tod because of his larger size.
Answer: As shown in Nicky's office, him and the models are professionals, judging from the different tools that they are using and a map of the Mallory Gallery. All they would have to do is watch and wait for the dogs to leave a specific area, and they would be able to get in because of how quiet they were while Kermit and friends were caught because of how much noise Animal made while trying to eat through the bars.
