Asterix live-action movie producer Claude Berri hoped to follow up the success of Asterix: Mission Cleopatra with a third film based on the book Asterix in Spain. Gerard Jugnot wrote the script and was to direct.

Uderzo and Anne Goscinny were "not interested" in the film. It is likely that script widely deviated from the book which they were not happy with, although no details about what these were emerged.
