EXCLUSIVE: Following a breakout run as the enigmatic Bob Benson on AMC’s Mad Men, actor James Wolk has signed with ICM Partners. Wolk joined the series’ sixth season and was nominated for the Satellite Award for Best Supporting Actor for the role before reappearing on the show’s seventh and final season.
