Mark Ruffalo Plays Twins In HBO’s “I Know”

HBO has handed out a green light to “I Know This Much is True,” the six-episode limited drama series adaptation of Wally Lamb’s bestselling novel.

“Avengers” alum Mark Ruffalo is slated to both executive produce and star as identical twin brothers Dominick and Thomas Birdsey in the series. The story follows their parallel lives “in an epic story of betrayal, sacrifice and forgiveness set against the backdrop of 20th century America.”

Acclaimed filmmaker Derek Cianfrance (“Blue Valentine,” “The Place Beyond the Pines”) penned, directs and executive produces the entire run. Also producing are Lamb, Ben Browning, Glen Basner, Gregg Feinberg and Anya Epstein.
