ACTRESSES Keira Knightley and Sienna Miller were real luvvies when they attended the world premiere in Scotland of their new film The Edge of Love.

Miller sported a black hat, Louis Vuitton shoes and a black dress by Jasmine di Milo, prompting Knightley to comment: “She’s the best looking date I could ask for!”

The biopic of Welsh poet Dylan Thomas biopic was penned by Knightley’s mother, Glasgow-born screenwriter Sharman Macdonald, and screened in the capital at the opening of the 62nd Edinburgh International Film Festival.

Movie fans queued for hours to see their favourite stars, including festival patron Sir Sean Connery, who had his arm in a sling.

Macdonald has been reported as saying she could not watch her daughter shooting the sex scenes in the film, but Knightley had a more relaxed attitude to appearing in a sex scene written by her mum.

“It certainly didn’t worry me that my mother knows what sex is,” she joked.

She also revealed she was told she would have to sing on set - in front of up to 200 extras only on the day it was being filmed.

“It was terrifying. My knees started buckling and the first couple of takes I sounded like a pubescent boy. Then somebody bought me a couple of shots of vodka and everything was all right after that.”

The film festival runs until June 29.
