Former ER star Goran Visnjic has signed on to play Dragan Armansky in Sony Pictures’ The Girl With The Dragon Tattoo, the David Fincher-directed adaptation of the Stieg Larsson bestseller. Visjnic’s character, the CEO of a security firm that employs Lisbeth Salander, is part of the entire trilogy and the actor has signed on for all three films. Daniel Craig and Rooney Mara star in the Steve Zaillian-scripted film, and Scott Rudin is producing. Visnjic, who was a frontrunner for the James Bond role that went to Craig, most recently completed the Mike Mills-directed Beginners and starred in the BBC miniseries The Deep. He’s repped by WME and Management 360.
