At some point, both Warner Bros. Television and ABC will be happy with who is leading its new series "V."

After holding the reins for just a single episode, Warner Bros. has removed "The 4400" executive producer Scott Peters from the showrunner position on "V" and replaced him with Scott Rosenbaum.

This is the second change at the top spot since production started on "V," which stars Elizabeth Mitchell, Morena Baccarin, Morris Chestnut and Scott Wolf. The pilot episode, which aired tonight on ABC, was done under the leadership of Jeff Bell. After Peters was given showrunner responsibilities, Bell -- who had worked on other shows such as "Harper's Island," "Alias" and "Angel" -- remained in an executive producer role following the change. However, with Rosenbaum coming on board, Bell is off the series, according to The Hollywood Reporter.

Rosenbaum currently is an executive producer on "Chuck," another Warner Bros. Television production that recently got good news from NBC with the announcement that it was moving up the season premiere of the show and ordering additional episodes. This was after "Chuck" reportedly had been on the bubble toward the end of last season, although some claim the fan movement to push for a "Chuck" renewal involving one of its main advertisers was nothing more than a network stunt to push buzz on the show.

Rosenbaum is still pretty new in the business, joining the writing staff of the F/X series "The Shield" in 2002 before being elevated to co-producer in 2004. He would finish with the series in 2007 as an executive producer.

He joined "Chuck" as a writer in 2007, and was named an executive producer on the show in 2008.

"V" airs Tuesdays at 8 p.m. ET on ABC.
