'Grimm': James Frain cast as Captain Renard's brother Eric

james-frain-getty.jpgWhile the first season just finished up on "Grimm," it's not too early to get a jump on next year. Zap2it has found out exclusively that James Frain ( "True Blood") has been cast as the brother of Captain Sean Renard ( Sasha Roiz) on the spooky procedural.

Frain will play Eric Renard in what's being described as a recurring guest star. The character, who doesn't have the greatest relationship with his brother, comes to Portland after a very bad creature makes its way into town. Needless to say, Eric has his own plans, and it looks like Nick ( David Giuntoli) is the target.

"Grimm" ended its first season with quite the bang. In what could easily be described as the worst day of his life, Nick has to explain to Juliette ( Bitsie Tulloch) his real history. At the same time, his mom, played by Mary Elizabeth Mastrantonio, makes an unexpected return.

For people who have missed out on the first season of "Grimm," the show is rerunning on Mondays at 10 p.m. ET on NBC.
