Mark Ruffalo Will Headline Adaptation of I Know This Much Is True for HBO

Ruffalo will reteam with HBO after starring in The Normal Heart for the new limited drama series.

Finding success with established film actors starring in limited series with the likes of True Detective and Big Little Lies, HBO has announced that they are developing a limited drama series with Avengers star Mark Ruffalo.

Ruffalo will star and executive produce an adaptation of I Know This Much Is True. The bestselling 1998 novel by bestselling novel and former Oprah’s Book Club pick by author Wally Lamb is described as, “an epic family saga that explores the American identity following the parallel lives of twin brothers Dominick and Thomas Birdsey throughout the latter half of the 20th century,” according to Deadline. Like James Franco on HBO’s The Deuce, Ruffalo will be performing double duty, portraying both brothers.

The project is being written and directed by Derek Cianfrance (The Place Beyond the Pines). Ruffalo, Cianfrance, and Lamb will all executive produce alongside Ben Browning and Glen Basner of FilmNation (Arrival, The Big Sick). I Know This Much Is True will mark the second collaboration with HBO for Ruffalo, who starred in and co-executive produced the feature The Normal Heart for the network, netting him an acting Emmy nomination.

Of course, Ruffalo will next be seen in Thor: Ragnarok, which hits theaters on November 2.
