Asterix and the Big Fight

Asterix and the Big Fight 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.
