In 2009, former journalist Martin Sixsmith wrote 'The Lost Child of Philomena Lee' - a heartrending tale of the forcible separation of mother and child by the nuns of an Irish convent, who, it turned out, had sold Philomena's son to a couple in America.

Four years later, this story is brought to life on the big screen, starring Dame Judi Dench as Irish lady Philomena, and Steve Coogan as Martin Sixsmith, who helped her discover what had happened to her lost son.
The film, also penned by Coogan along with Jeff Pope, and directed by Stephen Frears, opened to rave reviews at the Venice Film Festival, and will be in UK cinemas from 1 November.
