Oscar-winning director Paul Haggis was arrested in Italy on Sunday on charges of sexual assault and aggravated personal injury, police said.
Priya Chaudhry, an attorney for Haggis, said the Canadian filmmaker was "totally innocent" and was willing to cooperate with authorities.
He is totally innocent, and willing to fully cooperate with the authorities so the truth comes out quickly."
The woman who accused Haggis will also be questioned ahead of the trial, Negro said.
Haggis denied the original allegation and sued the publicist, Haleigh Breest, accusing her of trying to bankrupt him.
