A victim of disgraced Hollywood mogul Harvey Weinstein has alleged that he told her that all he wanted was "one thrust" as he prepared to rape her.

More than 100 women have come forward to report allegations of sexual harassment or assault by Weinstein over a period stretching back decades, although the majority of the cases did not lead to a direct conviction.

In February the 68-year-old was found guilty on two counts of sexual misconduct and was sentenced to 23 years in prison.

Weinstein's former assistant Rowena Chiu has now recalled the events of a night when she was left alone with the producer in a hotel room at the 1998 Venice Film Festival.

"He pushed me back against the bed and he parted my legs and he said, 'Just one thrust, just one thrust and it will all be over'," Chiu told a new documentary for Quest Red.

"He said, 'If you do this you can do anything you want in the film industry', he said he'd never had Chinese girls before. He said 'just one thrust and I promise I'll pull out'."

Harvey Weinstein airs Saturday, April 18 at 11pm on Quest Red.
