Actress Lena Headey, best known for her role as ruthless Cersei Lannister on Game of Thrones, has shared her own story of being victimised in Hollywood.

Headey, who has starred on the HBO series since it premiered in 2011, became the latest actress to allege that disgraced producer Harvey Weinstein sexually harassed her.

The Emmy-nominated actress recalled first meeting Weinstein at the Venice Film Festival in 2005, where her film The Brothers Grimm - distributed by Miramax - was showing.

"At one point Harvey asked me to take a walk down to the water, I walked down with him and he stopped and made some suggestive comment, a gesture," Headey said in a series of tweets, mentioning that she was sure it was all a joke.
