When Juliette Benzoni in 1968 saw the first time the movie version of Catherine (after her book series Catherine, il suffit d'un amour 1963) with Olga Georges-Picot in the leading role, she cried like a fountain. She had been shocked how the producer had changed her story. Instead of a knight from the middle ages, the hero Arnaud de Montsalvy was all of a sudden a revolting student in Paris. The end product had nothing to do anymore with the original story - and flopped at the cinema.
