Harvey Weinstein has been accused of rape, assault and sexual harassment by around 100 women

A hard-hitting documentary will expose the 'ritualistic humiliation' Harvey Weinstein is said to have inflicted on women.

A Panorama investigation airing tonight will use interviews with the disgraced media mogul's alleged victims to explore claims of rape and harassment as Hollywood prepares for its 90th Academy Awards.

The BBC programme features former head of production at Miramax, Paul Webster, who describes him as 'abusive and bullying in every aspect of his life'.

Weinstein, 65, has been accused of sexual harassment, assault and rape by around 100 women, including from global stars Rose McGowan, Asia Argento, Angelina Jolie and Gwyneth Paltrow, since October when revelations first broke.

Some cases date back to the 1980s while there are police inquires ongoing in LA, New York and London. He denies all allegations of non-consensual sex.

The 60-minute film, produced with PBS Frontline, builds a picture of Weinstein through interviews with alleged victims, former colleagues and other industry figures.

Mr Webster admits in the documentary that he 'didn't have to guts' to confront Weinstein.

'I think looking back that I did know and I chose to suppress it,' he said. 'I chose to hide from that fact. I think the deal I made with the devil was to my advantage.'

The attorney general who filed a lawsuit against Weinstein claims the case is one of the most despicable he has ever worked on.

Attorney General Eric Schneiderman filed the suit last month following the investigation into allegations of sexual misconduct.

Weinstein is said to have wept in front of one accusers, complaining: 'You don't like me because I'm fat.'

'It's sort of unfathomable,' he said. 'It is very difficult for anyone who looks at the documents that we've seen to, to believe that there wasn't at least some knowledge that he was engaged in sexual misconduct.

'We've never seen anything as despicable as this.'

The New York attorney general claims there was 'not one formal investigation' by the Weinstein Co into the producer's behaviour despite 'lots of complaints'.

Paul Webster, former head of production of Miramax, said he 'didn't have the guts' to confront Weinstein.

Among the alleged victims interviewed are actors Katherine Kendall and Sean Young, while Paula Wachowiak, a former intern at Miramax, recalled Weinstein laughing when she said he 'disgust(ed)' her.

Model Zoe Brock told documentary makers: 'I just remember feeling so small and so inconsequential and so powerless.

'I came out of the bathroom and he was apologising ... and he started to cry. And he said something that I have never forgotten and I never will for the rest of my days, in between his tears: 'You don't like me because I'm fat'.'

Gwyneth Paltrow is one of the many women who have come forward to make allegations about Weinstein

A spokeswoman for Weinstein told the film makers: 'Mr Weinstein categorically denies ever engaging in any non-consensual sexual conduct with anyone and any suggestion that he acted improperly to defend himself against such claims is simply wrong.

'Nevertheless, to those offended by Mr Weinstein's behaviour, he remains deeply apologetic.

'At no time has Mr Weinstein been charged with any crime and it is wrong and irresponsible to conflate clams of impolitic behaviour or consensual sexual contact later regretted, with an untrue claim of criminal conduct.

'Mr Weinstein categorically denies these claims and his lawyers will respond in the appropriate legal forum with evidence proving they are untrue.'

Weinstein: The Inside Story airs on Thursday night at 9pm on BBC One.
