"Considering I was not involved in Season 8, this new 24 event series gives me the chance for closure on a show that is very important to me," Cassar, who won two Emmys for the series, said. Added producer and showrunner Howard Gordon: "Jon was a profoundly integral part of 24 creatively and culturally. It doesn't feel like it would be 24 without him, and we're all just really thrilled to be working with him again."
The 12-episode event series is slated to return in May 2014 and run through the summer. Kiefer Sutherland will reprise his starring role as CTU agent Jack Bauer.
