So to clarify: Saying two different movies both of which has the "friend turns out to be bad" are copies is wrong; that's just not enough of a similarity to base a copyright case on. However, if you happen to find a way to patent it (which you probably could if there hasn't been prior art), you would be able to sue for patent infringement.
Doubtful. But, given that if diversity in movie plots benefits mankind (!) then offering an incentive to develop a new plot could be worth it. If the plot is entirely disclosed so that it can be used for free by anyone in a few years then is this not a benefit?
mluiten might be referring to the fact that copyright only applies to "original works of authorship fixed in a tangible medium of expression." (See http://www.copyright.gov/help/faq/faq-general.html)
That is, copyrights don't cover ideas, but creative works in some fixed form (e.g., a painting or a piece of software).
Say you've got a popular photo, you can transfer the litigious rights of it to a copyright troll and that troll will then sue everyone using it.
Kind of like what RIAA is doing.
