Here are three very good links to get you up to speed on the Sony hack and the movie The Interview.
This first link is a timeline of all the events that have unfolded.
The second link is an excellent point about risk and how Sony pulling The Interview from movie theaters may become a clarion call for tort reform (innocent third parties should not be liable to be sued because of something evil a nutcase does).
The third link is just fun. The Sony Hack gets the Taiwan animation treatment.
