Oh yeah, I remember downloading the trailers and adds for it, and the UK version of the Jango Fett TV spot had the headbutt removed. My Goldeneye (James Bond) DVD is also a region 2, and at the end of the movie there is a fist fight that originally had a few headbutt in it that were removed. On the commentary track for Goldeneye the director actually mentioned how they had to be cut out for the European release, because a few countries had strict rules regarding headbutts, and the film would have had to jump up a rating had they left them in. So that also explains why AOTC had to have the headbutt removed. I guess in America we are more tolerant of violence, but less tolerant of sexual things. Funny stuff.
Were any of the OT movies release in clear cases? Are many other movies released in clear cases over there? Or is it pretty uncommon. In the states movies typically all come in the black cases, but on some rare occasions they will do something different to make them stand out. For example, Terminator 2 had a release that came in a metal slip case, the Lord of the Rings DVDs each came in a different colored DVD case instead of the standard black DVD case (FOTR green; TT red; ROTK blue), and many kid's movies (especially Disney) tend to be given white cases.
