Madman Screening Room's website works better now, so I managed to capture audio from the English trailer of "Asterix vs Caesar" that was in that site. As you can see, they dubbed the trailer way before possessing the full movie, in which they improved their accents and translations. Same happened with "Asterix in Britain". Trailer in origin language: https://www.youtube.com/watch?v=VGrkqnvufw4 And to prove the English trailer is real: http://www.madman.com.au/videos/view/1447/asterix-versus-ceaser (c) Gaumont Multimedia/Les Editions Albert-Réne
