Saving Grace - Holly Hunter

There's no Saving Grace: Holly Hunter's cop drama will wrap up next summer after its third season, TNT announced.

The network had originally ordered a split 15-episode third season, with nine episodes currently running this summer and six to run in the winter. TNT has now tacked on three more episodes to the remaining six to allow producers to tie up loose ends. The last nine episodes will air in summer 2010.

"Since Saving Grace began in 2007, the series has both challenged and entertained viewers in ways few other shows on television ever dare," said Michael Wright, TNT programming chief. "The show's continued success is thanks to the amazing talents of Holly Hunter and Nancy Miller, along with a tremendous ensemble cast and a highly skilled production team. They have taken us on a unique journey, and we look forward to seeing where it will ultimately lead."

A reason for the cancellation was not given, but the series, with Oscar winner Hunter in the lead, is expensive to produce.

Grace, which follows Hunter's promiscuous, tough-as-nails Det. Grace Hanadarko, has enjoyed critical acclaim and solid ratings since its debut. Hunter earned her second-straight Emmy nomination for the role last month and the series has averaged 3.5 million viewers going into Tuesday's summer finale.
