Butler, 42, entered the world-renowned Betty Ford Centre in California three weeks ago after reportedly "relying too much on prescription drugs" and in an effort to "head off a full-blown addiction".
Butler's problems were said to stem from his battle to recover from injuries he suffered while filming the Spartan epic, 300, in 2006.
