CBS gave "Unforgettable," which was the highest-rated cancellation last season, a reprieve. But unfortunately, most of its cast will not return.

Stars Poppy Montgomery and Dylan Walsh will be back when the show returns next summer, but outside of Jane Curtin (who signed on midway through Season 1), it will be a whole new look on-screen.

Gone are Daya Vaidya, Kevin Rankin, Michael Gaston and Britt Lower. They played, respectively, Nina Inara, Roe Saunders, Mike Costello and Tanya Sitkowsky. All of the actors except Lower appeared in every episode. Lower was in just 12.

Gaston was likely the most well-known actor in the bunch to leave. A character actor, he has appeared in a number of shows in a recurring status including "The Mentalist," "Rubicon," "Damages" and "Law & Order." He was also a regular on the short-lived CBS series "Jericho" as Gray Anderson, a mayoral rival in the town who continued on politicking even after the nuclear bombs fell.

Rankin was a series regular in "Friday Night Lights" and "Trauma," and was in the short-lived NBC series "Bionic Woman." He also most recently appeared in "Justified."

Vaidya was a character actress that had guest roles in a number of series, but wasn't a series regular since "Hyperion Bay" in 1999 with Mark-Paul Gosselaar.

It's not clear who CBS plans to bring in to fill out the support cast, but it will likely be a little more bare-bones than the first season of "Unforgettable," since budget will be smaller for a summer series. But "Unforgettable" fans are simply happy the show is back.

Last year, "Unforgettable" averaged a 7.2 rating/12 share average, according to Fast National overnight ratings from The Nielsen Co. It was ranked No. 8 at CBS, No. 2 among new shows, and No. 11 overall. Yet, it finished 6 percent behind its timeslot from the year before, and would lose 26 percent of its "NCIS: Los Angeles" lead-in.

The series is about a former New York police detective that has the rare ability to remember everything she sees. She then uses that ability to solve crimes for the New York Police Department.
