On the day of its premiere Tuesday, ABC’s “V” underwent a shake-up in its top producing ranks, Variety reports.

Scott Rosenbaum ("The Shield," "Chuck") has been named showrunner and executive producer. He replaces Scott Peters, who will remain an executive producer, as will Jace Hall. Executive producer Jeff Bell left the show.

The show got good reviews, but only four episodes will air before the show goes on hiatus. It will return in the spring.
