Ewan McGregor has told of his desire to be in the follow-up to movie hit Trainspotting.
The actor – who played Mark 'Rent Boy' Renton in the original film – said he had not been officially approached but was keen to star in the screen adaptation of Porno.
There have been discussions about bringing the book by novelist Irvine Welsh to the screen in 2016.
McGregor (42) affirmed his interest in the film as he attended an investiture ceremony at Buckingham Palace to collect his OBE, awarded for services to drama and charity.
He said: "I have not been approached officially, but I would be up for it."
McGregor, who attended the ceremony in a kilt, said in 2009 that he was not keen on a reunion unless the story justified it.
And he added: "I didn't think the book (Porno) was very good."
