EXCLUSIVE: Eddie Marsan and Dash Mihok are set to co-star opposite Liev Schreiber in Showtime’s drama pilot Ray Donovan. Created and executive produced by Southland creator Ann Biderman, executive produced by Mark Gordon and Bryan Zuriff and to be directed by Allen Coulter, the Showtime-produced project takes a novelistic look at contemporary Los Angeles. A dark family drama with comedic undertones, the show centers on Ray (Schreiber), a professional “fixer” for LA’s rich and famous who can make anyone’s problems disappear, except the ones created by his own family. Paradigm-repped Marsan will play Ray’s brother Terry, a skilled former boxer who despite his Parkinson’s diagnosis hasn’t lost his fighting spirit and continues to train others in his gym. Mihok, repped by Gersh and Untitled, will play Bunchy, Ray Donovan’s younger brother — a troubled alcoholic who is haunted after being sexually abused and continues to struggle with sobriety despite the help of his two brothers. In addition to Schreiber, Marsan and Mihok join recently cast Paula Malcolmson. British actor Marsan co-stars in the Sherlock Holmes movie franchise and was also recently seen in War Horse. His upcoming movies include Jack The Giant Killer and Snow White And The Huntsman. Mihok, who recently recurred on NBC’s Prime Suspect, will next be seen in David O’Russell’s The Silver Linings Playbook.
