I've read enough reports to believe the Russell Brand story is true.
It's a disgusting power play. He's a powerful 'star" (I use the word very very loosely!), she is a lowly wardrobe girl. Who has the power on the film set?
Yes, she could have called the police, reported him, had him arrested. So could every other person on that film set who was aware of what he was doing. Actually, Billy Connolly could've called the police. Every single person on that film set who watched/heard and said nothing are as culpable as he is, in my opinion.
But they didn't, because Russell Brand=Talent=Money. And that has far more currency in the film industry than common decency or pesky annoyances like the Law.
If he had been arrested, she would never have worked in the film industry again. It makes me very very sad that this is so. This isn't the world that I want for my daughter and son
