A year ago Sony suffered a major hack that prompted a string of events that seemed worthy of a tragic-comic blockbuster, in response to the studio's comedy about North Korea, "The Interview."

The hack revealed the personal information of tens of thousands of people, exposed embarrassing email exchanges between high-powered actors and executives, cost the studio tens of millions of dollars, and one top executive lost her job. Plus, it kicked off fears of a terror attack on movie theaters so serious that all the major chains pulled the film, which prompted Sony to break from industry tradition and do the biggest day-and-date distribution of a film ever. This comedy became a beacon for free speech advocates and even President Barack Obama. And Hollywood was forever changed.
