The 42-year-old actor received treatment for prescription drug problems in February and he is set to be part of the film which sees a team of FBI agents going after their most wanted man, domestic terrorist and survivalist James Tollan, in the North Carolina wilderness, reported Contactmusic.
Butler will help the FBI try to catch the elusive killer, who has managed to avoid arrest with the support of the local population. Michael Shamberg and Stacey Sher are producing the project and "The Crazies" director Breck Eisner is helming the movie, which is expected to start production at the end of the year.
