Iranian-born character actor Shaun Toub (Iron Man, The Last Airbender) has been added to the cast of another HBO drama series, the upcoming Luck, as a recurring. Luck, a David Milch/Michael Mann collaboration starring Dustin Hoffman, takes a provocative look at horse racing -- the owners, gamblers, jockeys and industry players. Abrams Artists-repped Toub will play Doctor Khan, a local emergency room doctor with a surprisingly complicated backstory.
