"One of the things I like is that Sean is not [24 character] Jack Bauer," he said. "You can start a character way behind the start line compared to [how Bauer was in] the first season of 24."
Katz also insisted that the show will not employ Lost-style flashbacks in the first season.
"We made an early decision that episodes will only move forward in time," he confirmed. "We have talked about taking an episode to do an origin story or a crazy changeup but that won't happen in the first six."
