See Mark Ruffalo and Mark Ruffalo as twin brothers in new HBO limited series

Not to be outdone by his Marvel movie co-star Paul Rudd, who took on two roles in Netflix’s Living With Yourself, Mark Ruffalo is pulling double duty this year in HBO’s miniseries I Know This Much Is True.

The first batch of photos debuted on Wednesday, timed to the home box office network’s Television Critics Association presentations. Ruffalo, who last appeared on the big screen in Todd Haynes’ Dark Waters, can be seen playing two very different but identical twin brothers Dominick and Thomas Birdsey.

The six-part series, written and directed by Derek Cianfrance (The Place Beyond the Pines), takes viewers to different points in the brothers’ lives to tell a moving tale about betrayal, sacrifice, and forgiveness. The story is based on author Wally Lamb’s book I Know This Much Is True: A Novel (P.S.).
