Jennifer Beals, Michael Madsen

Michael Madsen has booked a two-episode arc on Fox's The Mob Doctor, TVGuide.com has learned exclusively.

Madsen will play Russell King, a veteran criminal whose crimes require a certain flair and professional expertise. On the night of a big job, King has a flare-up of back pain and discovers he requires immediate surgery. We're guessing The Mob Doctor herself, Jordana Spiro's Grace Devlin, will be called on to help.

Madsen's character will first appear on this season's ninth episode.

In other Mob Doctor casting news, Jennifer Beals will also join the cast for "at least three episodes" beginning in late November. The former L Word star will play Celeste LaPree, a former call girl-turned-high-class madam who used to date Constantine Alexander (William Forsythe) before he went to prison. Celeste is now married to a mafia boss who runs Chicago's North Side, but, according to creator, Josh Berman, she may be more than meets the eye.

"We wrote the role of Celeste LaPree specifically with [Beals] in mind," Berman said. "She's gorgeous, empowered and strong. ... In a world of organized crime, dominated by men, Celeste LaPree has made a name for herself. Unbeknownst to those around her, she has a secret agenda that may change the face of organized crime in Chicago."

The Mob Doctor returns on Monday, Nov. 5 at 9/8c on Fox.
