David Tennant has revealed how he had to work from multiple scripts on new crime drama Broadchurch, as the ending was being kept top secret.
The former Doctor Who actor stars with Olivia Colman, Pauline Quirke, Vicky McClure, Jodie Whittaker and Andrew Buchan in the ITV show about the investigation into the discovery of a young boy's body on a beach.
David told The Sun the ending was kept secret even from the cast during filming.
He revealed: "I had two scripts to look at and knew that other scripts would be appearing throughout the process. But we wouldn't get final scripts until months into the shoot. It was a gamble.
"But the fact that I read it from cover to cover in one pass and was left at the end of the first episode desperately wanting to know what happens next was telling.
"That initial response is always worth noting. If it grabs you and you want to know more, and if you're intrigued by the characters in that first moment, that's always something to be pursued."
He added: "When you're playing those initial interviews with characters and you genuinely don't know what the truth is, you can't load those scenes with 'actorly' tricks.
"You have to play it for what it is, which can only make it more real. You can be as exasperated about the mystery of the characters as the audience will be."
He went on: "It's great to be part of something where all the characters have powerful stories to tell. There's the whodunit aspect but there are other stories going on and such wonderful people portraying those parts."
