Helene Darras said that
Depardieu assaulted her while filming a movie in 2007,
Paris prosecutors said, confirming a report from broadcaster France 2.
Investigators were studying the complaint, which likely falls under
France's statute of limitations, to decide whether or not to launch a probe.
Depardieu's lawyer Christian Saint-Palais could not immediately be reached for comment.
Darras told France 2 that Depardieu groped her when she was aged 26 and appearing as an extra in the film "Disco".
The older man "ran his hand over my thighs and my buttocks" then "said straight out: 'Do you want to come to my dressing room?'," she added.
Darras rejected the alleged advances, but "that didn't change anything," she went on. "He kept groping me between takes".
