This is the year 50 before JC. All the Gaul is occupied by the Romans. All the Gaul? No! A little village populated by some irreducibles Gallics resists again and always to the invader. This situation gets on Jules César's nerves who's starting to compare these Gallics as gods. To have proof of this, he sets them 12 works. Astérix and Obélix are chosen to take up the challenge... This animation film isn't an adaptation from one of Astérix' albums, it's an original screenplay that inspired from the Greek mythology with Hercule's works. The movie is a pleasant surprise because the animation is more careless than in Astérix' previous adaptations for the cinema, although it's a bit basic. Concerning these "works", of course they're fanciful and eccentric but they're irresistibe, varied, full of modern anachronisms (like the chips in the sixth work when Obélix must eat a pantagruelian meal). Besides, the anachronism is a common thing in Astérix' adventures.
The best moments of the movie are the pantagruelian meal, the sequences of the hypnosis and the crazy flat. At the end, in spite of tiresome sequences, peculiar to Astérix's adaptations, I think about the (useless) battle against the Romans at the beginning, the movie is a happy entertainment and the best animation film with Astérix.
