It's official: Sony have found The Lost Symbol. Not that it was hard to find - it was sitting on their desk all along. Ever since Dan Brown's book came out, it's only been a question of when the studio would start writing it for the screen.

And so Steven Knight (of Dirty Pretty Things) is on script duty, adapting the third outing for Robert Langdon - sure, Angels and Demons only took $486 million compared to The Da Vinci Code's $760m odd, but that's still enough money to cover Tom Hanks' haircut. Presuming they can convince him to sign on again. Then it's just a case of getting hold of Ron Howard. That shouldn't be too hard.
