Celador Films, the film arm of the UK TV outfit behind Who Wants To Be A Millionaire', has added two non-fiction books to its bustling development slate - porn trade story Once More With Feeling and professional poker player book Big Deal.

Once More With Feeling is Victoria Coren and Charlie Skelton's true account of their adventures in the porn trade. Screenwriter Erin Cramer is working on the adaptation, which is billed as "a romantic comedy with extra sauce."

Big Deal is Anthony Holden's account of his year as a professional poker player, bookended by his two doomed attempts to win the World Series of Poker in Las Vegas. Celador aims to develop the story as a midlife crisis comedy.

Celador, which moved into film with Stephen Frears' Dirty Pretty Things, is also starting shooting next week on romantic drama A Way Through The Woods, the £5m directing debut of Oscar-winning writer Julian Fellowes starring Emily Watson, Tom Wilkinson and Rupert Everett.

Other projects in development include The Dark, writer-director Neil Marshall's follow-up to Dog Soldiers, and a comedy by television writer Russell T Davies based on the much-publicised Who Wants To Be A Millionaire' fraud case.

"[Celador chairman] Paul Smith's genuinely entrepreneurial business model enables us to operate with real independence and to generate great momentum behind our projects," said head of film Christian Colson. "We hope that this is just the beginning, and that with this formula we can continue to attract the UK's best writers, directors and actors."
