She was also known for her work as a voice artist, having dubbed films, such as, Robert Altman's Popeye (1980), The NeverEnding Story III (1994) and Hackers (1995), and animated television series, Teenage Mutant Ninja Turtles and Totally Spies!

She may have been best known for playing Catherine Valmont in 1982 horror La Morte Vivante (The Living Dead Girl), a film from Jean Rollin.

Françoise approached the part skeptically as she remembered that at that time she was, "aggressive against people but also a bit confused" due to the death of her brother.

"I liked the feel of these B movies, especially horror", Françoise noted to Encore, which perhaps explains why she became so popular to several of the most noteworthy genre directors of the late 1970s.

The night shoot on the film was mostly difficult and there were many problems with the special effects but, despite some disagreements, she liked and admired Rollin and admitted to Encore that, "he is really nice and is very much there".
