Astérix et le coup du menhir
Asterix and the Big Fight (Astérix et le coup du menhir) is a 1989 French-German animated film directed by Philippe Grimond and produced by Yannick Piel. It is based on the Asterix comic book series. The film has a different plot from the book of the same name. It combines plot elements from Asterix and the Big Fight and Asterix and the Soothsayer. Although there is plenty of fighting — as usual for an Asterix story — the actual fight that the story is named for is not part of the movie's plot. The novelization was titled "Operation Getafix" (the German translation of the film was Operation Hinkelstein, a hinkelstein being a menhir).
The Romans capture Druid Getafix, as part of their plan to deprive a rebel village of Gauls from the magic potion that gives them super-human strength. When the village attempts a rescue, Obelix accidentally hits Getafix with a menhir in the resulting chaos, causing him to be struck with amnesia and insanity. As the village comes to grip with this, a travelling soothsayer named Prolix arrives and begins deceiving some of the credulous villagers into believing a number of prophecies he predicts, despite the fact he is a fraud.
