Amy Acker Upgraded to Series Regular on 'Person of Interest'

It was announces yesterday during the 2013 Person of Interest panel at San Diego Comic-Con that Amy Acker would be joining the cast as a series regular. The mysterious character of Root will be on the show full time in season 3. She joins Sarah Shahi as Shaw who has also been upgraded to series regular for the new season.

Check out this new video to come out of the Person of Interest panel. It shows very little new footage but pokes fun at the recent discoveries with the NSA and PRISM.

The Machine is real!
