Depardieu, 76, a towering figure of French cinema, is accused of sexually assaulting two women on a film set in 2021. This is the first time the actor, who has faced a number of sexual assault allegations in recent years, is standing trial.
Depardieu has admitted to grabbing one of the women by the hips, but denied it was assault. His lawyer has said the accusations against his client are false and investigators biased.
Prosecutors made the request in court, media reported. The prosecutor's office did not immediately respond to a request for comment.
