The overall plot of this animated version of Astérix chez les Bretons is faithful to that of the book. As the latter is perhaps the best of all the Astérix volumes, this film could fare badly in the comparison. But whereas most of the Astérix films lose much in the transition to a dumbed-down, vaguely Hollywoodesque cartoon that I suppose is meant to appeal to children, Asterix in Britain manages to retain much of what made the original (written and drawn) version great. I haven't yet listened to any of the dubbed versions of the film, but the French is particularly clever in using native English speakers to play the roles of the Bretons.
