EXCLUSIVE: In her first TV series gig, Joan Allen is set to do a multi-episode arc on HBO’s upcoming series Luck, joining a cast led by Dustin Hoffman. Luck, a David Milch/Michael Mann collaboration, takes a provocative look at horse racing — the owners, gamblers, jockeys and industry players. ICM-repped Allen will play a woman who runs a program that uses prison inmates to care for broken-down racehorses. On TV, the Oscar-nominated actress has done only a handful of TV movies, most recently playing the title role and executive producing Lifetime’s Georgia O’Keefe last year, which earned her an Emmy nomination. Luck is currently in production on the first post-pilot episode, which is being directed by Terry George.
