As you may or may not have seen, a number of outlets have been sent a mysterious metal box containing contents from the new Fox series Alcatraz. Produced by J.J. Abrams, the hook of the show centers on the sudden appearance of a number of inmates from Alcatraz prison who mysteriously disappeared decades ago. The contents of the metal case sent to Collider headquarters include a prison cell key, an Alcatraz tour book, a page from a magazine touting Dr. Diego Soto’s (Jorge Garcia) non-fiction book Inmates of Alcatraz, a newspaper clipping, and some postcards. It’s pretty impressive stuff. Hit the jump for more, including images of the box’s contents.
