Keira Knightley and Sienna Miller are among the stars who attended the opening night of the Edinburgh International Film Festival.
It is the first time in its 61-year history the event has been held outside the main festival month of August.
The opening night gala featured the World premiere of the Dylan Thomas biopic - The Edge of Love.
The film, which stars Knightley, was written by her mother, Glasgow-born playwright Sharman MacDonald.
Miller plays Caitlin, the wife of Welsh poet Thomas and Knightley is Vera Philips, his childhood sweetheart.
Knightley insisted she did not feel under any extra pressure starring in a film penned by her mother and said she was "very proud" of it.
Her mother has been reported as saying she could not watch her daughter shooting the sex scenes in the film.
But Knightley appeared to display a more relaxed attitude to appearing in a sex scene written by MacDonald.
"It certainly didn't worry me that my mother actually knows what sex is," she joked.
"It's a story about relationships. It's a story about how friendship can be ruined over an act of betrayal in the form of sex.
"You're not really going to get out of the fact that there is going to be sex involved in it."
However, the Pirates of the Caribbean star revealed she was "terrified" when she was told she would have to sing on set.
She said: "I thought I was going to die. My knees actually started buckling and the first couple of takes I sounded like a pubescent boy.
Festival patron Sir Sean Connery had his arm in a sling
"Then somebody very kindly bought me a couple of shots of vodka and everything was all right after that."
Director John Maybury said he was "incredibly honoured and flattered" that his film was opening the festival.
He said: "I think it's one of the best festivals in the world. Edinburgh has been very good to me."
The 62nd Edinburgh International Film Festival will show 142 features from 29 countries during its run. There will be 15 world premieres and 72 UK premieres.
EIFF patron Sir Sean Connery was among the guests at the premiere.
He turned up with his arm in a sling.
The Bond star gave no comment to the waiting media, but waved at cheering fans who asked if he was feeling ok.
Movie fans had queued for hours in advance to catch a glimpse of their favourite stars, such as Matthew Rhys and actress Joely Richardson, who is judging an award at the festival.
Knightley and Miller were inseparable on the red carpet as they posed for photographs and gave interviews before going in to see the finished film.
