Sons of Anarchy

Adam Arkin has joined the cast of Sons of Anarchy.

On the underrated FX hit, Arkin has signed on multi-episode arc as Ethan Zobelle, a season-two antagonist for SAMCRO.

According to E!, the character will be quite a departure for the typically mild-mannere Arkin.

Zobelle is a as a white supremacist who arrives on the scene to open a new a cigar shop. As viewers know, Ron Perlman's Clay Morrow loves himself some fine cigars. He doesn't love ultranationalist thugs, however, so expect skulls to be cracked before season's end.

The second season of Sons of Anarchy is likely to premiere in September.
