Australian star Rebel Wilson has revealed how she was sexually harassed by a Hollywood star and top director.

As more tales of sexual harassment come out of Tinseltown – including accusations against Richard Dreyfuss and Star Trek‘s George Sakei – Wilson took to Twitter to tell her own story.

“I’ve been away in a ‘bubble’ of sorts creating new comedy overseas but it’s so hard to hear all these stories relating to sexual harassment and assault in Hollywood,” she said.

“As you guys know, I’m a pretty strong and confident person but even I have a story to tell.”

Wilson revealed she had been propositioned by a star, but chose not to reveal his name.

“A male star, in a position of power, asked me to go into a room with him and then asked me repeatedly to stick my finger up his ass,” she wrote in shocking detail.

“All whilst his male ‘friends’ tried to film the incident on their iPhones and laughed.

“I repeatedly said no and eventually got out of the room.

“There’s a generation of Hollywood powerbrokers who’ve acted like it’s still the Stone Age, and as Cameron William writes, it looks like they’re no longer going to get away with it.

“I called my agent immediately and my lawyer made a complaint with the studio — basically to protect myself that in the event something similar ever occurred I’d be able to walk out of the job and not obliged to return.”

Wilson said she was later threatened by one of the star’s representatives to “be nice and support the male star”.

“I refused. The whole thing was disgusting,” she said.

“I’ve told hundreds of people in the industry the story in more graphic details, basically to warn them off this individual.”

Wilson also claimed she had a “hotel room encounter” early in her career with a top director.

“I thought we were there to talk comedy,” she said.

“Nothing physical happened because the guy’s wife called and started abusing him over the phone for sleeping with actresses and luckily she was yelling so loud that I could hear her and I bolted out of there immediately.

“I was so naive and the thought of anything happening apart from ‘work talk’ didn’t even cross my mind.

“I will no longer be polite.”

Wilson said she grew up in a “pro-female” environment, had a strong sense of self and had even taken self-defence classes.

“I had the ability to escape both incidents. I realise not everyone is as lucky,” she said.

“To hear how prevalent sexual harassment and assault is, is just so saddening.

“I know my stories aren’t as horrific as other women and men have described — but if you’ve ever experienced anything like this I feel for you and can relate on some level.

“I know, moving forward, that if I witness this behaviour, whether it happens to me or someone I know, I will no longer be polite. Interpret that as you will.”
