Who Will Be Allowed To Watch The Watchmen?

[cross-posted at Austro-Athenian Empire]

Another gift from IP: Fox is trying to block the release of this cool-looking movie based on one of the greatest comic books of all time. (Conical hat tip to Geoff Plauché.) Rumor has it that the Tolkien estate is likewise trying to block the upcoming Hobbit movie(s).

Note: for those who support IP, but do so on consequentialist grounds (mainly incentival) rather than rights-based ones, wouldn’t it be reasonable to allow the copyright holder only to demand a percentage of the profits, and not be able to block its release absolutely as Fox and the Tolkien estate are apparently seeking to do?
