adam arkin gi 'Justified': Adam Arkin guest starring as Theo ToninAdam Arkin’s trading in his “Justified” director’s chair for a spot in front of the camera: According to EW, he’s guest-starring in two episodes of the FX show this season as Quarles’ boss Theo Tonin.

Arkin has directed five episodes of “Justified,” including the Season 1 finale. He’ll be appearing in episode 311 and the Season 3 finale.

Executive producer Graham Yost tells EW that viewers will get more back story on Quarles and Theo in episode 310.

“Theo saved his life, but in a weird way,” Yost says.

He also adds that Arkin will have a unique look for his “Justified” acting debut.

“I don’t want to give it away. There is a physical tweak that Adam asked for,” he says. “Adam wanted to be distinctive, so when you see it, it’s like, Oh wow, that’s pretty wild. He’s not dressed as a pirate or anything. But he looks cool.”

We wonder if the physical tweak has anything to do with aging Arkin up a bit. Theo Tonin’s son Sammy just arrived in Harlan and is played by Max Perlich, who is not that much younger than Arkin.

“Justified” airs Tuesday nights at 10 p.m. ET/PT on FX.
