Naomie Harris

Anti-harassment and bullying campaign group UK Time's Up proposed the idea.

Knightley said: "For anyone to fulfil their creative potential there cannot be fear or disrespect of any kind."

Harris added that "no-one should go to work fearful of harassment, bullying and abuse".

UK Time's Up is working with Creative UK, which promotes the development of creative companies, to agree a plan of action. They are also speaking with representatives from the music, TV, film, theatre, advertising, video games, and fashion sectors.

The 40-year-old Moonlight star was speaking after she was awarded an OBE by the Queen at Buckingham Palace.

"I really don't think that they've moved on from Daniel," she said.

"I think there's a very good chance that Daniel will come back. I think it's way too early to be thinking about other people at this stage."
