Asterix and the Big Fight (in , literally Asterix and the menhir blow) is a 1989 French animated film directed by Philippe Grimond and produced by Yannick Piel. It is the sixth animated film based on the Asterix comic series. The story combines the plots of Asterix and the Big Fight and Asterix and the Soothsayer: despite sharing the same English title as the former book, the film is primarily an adaptation of the latter and does not involve the titular "Big Fight". In the film, Getafix is accidentally made insane and amnesiac by Obelix, forcing Asterix to try to cure him as his village is deceived by a fraudulent soothsayer that works for the Romans. A novelization of the film was released in English under the title Operation Getafix, possibly to avoid confusion with the original comic book but generating instead confusion as to the film's title.

Plot

The Romans try to 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 Asterix and Obelix attempt a rescue, Obelix throws and accidentally hits Getafix with a menhir in the resulting chaos, causing him to develop amnesia and insanity. While the village comes to grip with this, Prolix, a conman posing as a soothsayer, arrives during a storm and begins deceiving some of the superstitious and credulous villagers into believing a number of his prophecies, which he predicts in exchange for food and drink (later gold).
