I am adamant that I pick up the OAR version of a film when I buy it on DVD and this has sometimes led to me buying DVDs from overseas (to avoid an incorrect aspect ratio on the local DVD release). However, as I've said in the Harry Potter threads, I would really like to see some of the "more visual information" versions of Super35 films. James Cameron is probably the most widely known director to use Super35 and seeing any of his films like this would be cool.
