Rosenbaum, an executive producer on NBC's Chuck, has stepped in to replace Scott Peters as showrunner. Peters will remain as an executive producer, along with Jace Hall.

This isn't the first change for the series. In September, the network announced that V, which is shot in Vancouver, would go on hiatus after Episode 4, then continue airing the remaining nine of the original 13-episode order after the Winter Olympics, which run Feb. 12-28.

V premieres Tuesday, Nov. 3 at 8/7c on ABC.
