[Q]: In The Wolfman (2010) UNRATED, the asylum doctor tried treatment for Lycanthropy very well on Larry Talbot. But again he transformed into a wolf at full moon, kills some doctors and escapes from the place. Why didn't the treatment for Lycanthropy work?
[A]: Why didn't the treatment for Lycanthropy work?

[Q]: According to IMDb: Aliens are far more dangerous, they have no fear, can lose most of their limbs and still pose a major threat, they have acid blood, can kill with their claws, tails and teeth and can see predators even when they're cloaked. I've never heard that they can see predators, especially when they're cloaked... Are there direct references/examples to this in any of the AVP movies?
[A]: Can Aliens see cloaked predators?

[Q]: I have always wondered what techniques directors use to get amateur actors, especially young ones, to cry. How can someone surrounded with so many film crew and cameras can concentrate enough and feel so sad that s/he can possibly burst into tears? In general, is crying in a movie scene (with real tears) something that can be learned by practice or is it something that only talented people can perform?
[A]:
What techniques are used by directors to make an actor cry?
