This looks like quite a hilarious, silly film. Obviously, it's based on the popular comic book series by the same name. I've never read the comics in either French or English (not really my type of thing) so I'm not sure I'd watch this movie but Asterix's costume in this film is hilarious, it looks exactly like his comic book character! I'm sure those who enjoyed the comics would love this film.
