EXCLUSIVE: Clifton Collins Jr has joined ABC’s upcoming drama series Red Widow as a series regular. Based on the Dutch series Penoza, Red Widow centers on Marta Walraven (Radha Mitchell) who, after her gangster husband is brutally murdered by a rival cartel, takes on the gangsters and the FBI to unveil the truth about her husband’s death. Collins will play FBI agent James Ramos. He was originally approached to play the role in the pilot but wasn’t available. Mido Hamada was cast in the part, which is now being recast. Collins Jr, repped by APA and Industry Entertainment, just wrapped the Guillermo del Toro/Warner Bros feature Pacific Rim and the Taylor Hackford-directed Parker.

British actress Lara Pulver (MI-5) has been added as a series regular to another new drama series, Starz’s Da Vinci’s Demons. Written by David S. Goyer, Da Vinci’s Demons is a historical fantasy, following the “untold” story of the world’s greatest genius Leonardo da Vinci (Tom Riley) during his turbulent youth in Renaissance Florence. Pulver will play famed enchantress and political machinator Clarice Orsini, aristocratic wife of Florentine ruler Lorenzo Medici. The actress, known to U.S. audiences for her arc on True Blood, playing fairy Godmother Claudine Crane, is riding high on her talked-about guest stint as femme fatale Irene Adler in the opening episode from Season 2 of the BBC/PBS limited series Sherlock. Pulver, repped by Management 360, Paradigm and Independent Talent Group, was nominated for an Olivier Award for her performance in Parade on the West End.
