 There are actually 3 significant versions of this film. The version that is  available on DVD and at Film Festivals is the "restored" version mentioned  above. The Criterion laserdisc consists of Orson Welles American version of  the film in which he completely overdubbed Desdemonas voice with a new  actress and overdubbed many characters including Roderigo with his own voice.  In addition this version contains written credits instead of spoken and has  many alternate shots. The original Cannes version was shown once on British  Televison in the early 80s and is very difficult to find.
