Goran Visnjic, the former ER star, has signed up for the adaptation of The Girl With The Dragon Tattoo, according to reports.
The Croatian-born actor, 38, is being tipped to play Dragan Armansky in the Sony Pictures film, adapted from the Stieg Larsson best-seller.
Goran's role is that of the chief executive of a security firm that employs the story's heroine Lisbeth Salander, in the movie directed by David Fincher.
The actor has signed on for the whole trilogy, Deadline said.
Daniel Craig (disgraced journalist Mikael Blomkvist) and Rooney Mara (Lisbeth) star in the hotly-anticipated film.
Goran recently completed Beginners alongside Ewan McGregor and starred in the BBC miniseries The Deep.
