Depardieu's lawyer, Herve Temime, said at the time that the actor "absolutely denies any rape, any sexual assault, any crime" and dismissed the complaint as "groundless".
But the young woman relaunched proceedings by acting as an "injured party", which according to French law nearly always leads to a case being re-examined by a judge.
A source close to the case claims that Depardieu is a friend of the actress' family. They also said there was "nothing professional" about the incident, although some reports suggested Depardieu and the actress were rehearsing a theatre scene.
The actress' lawyer Elodie Tuaillon-Hibon said she hoped her client's "private sphere will be respected" as the case continues.
Depardieu is known as a stalwart of French cinema due to his film roles such as Cyrano de Bergerac, Jean de Florette and Camille Claudel. He has also had a successful international movie career, making over 180 films working with directors like Peter Weir and Ridley Scott.
He sparked a huge outcry in 2013 by leaving France and taking Russian nationality to protest at a proposed tax increase on the rich in his country. Russia's president Vladimir Putin hosted him for dinner to present him with his Russian citizenship.
The French actor divorced his first wife, actress Elisabeth Guignot, in 1996. He then dated Carole Bouquet, also a successful French actress, from 1997 to 2005.
