Movie mogul Harvey Weinstein has pleaded not guilty to rape and sexual assault charges after arriving at a New York court.

They are the first cases involving the disgraced producer to be tested in criminal court since scores of accusers emerged last year, documents showed.

Wearing a dark suit, he appeared to struggle to get out of a black SUV with his legal team before walking through a media scrum to reach the entrance of the court.

Weinstein seemed to be limping, as he did when he handed himself in to police, and rubbed his hands together as photographers took pictures of his arrival.

The 66-year-old has said through his lawyer, Benjamin Brafman, that he has never had non-consensual sex .

His appearance in Manhattan Supreme Court on Tuesday morning comes after a grand jury indicted him last week in two cases.

Weinstein turned himself in at a New York police station on May 25, and was taken to court in handcuffs for his initial arraignment.

A judge ordered him released on a $1 million cash bail on condition that he surrender his US passport and agree to wear a location-tracking device.

He was ordered to remain in New York state or Connecticut.
