Actress Anne Hathaway approves of director Christopher Nolan's unusual ploys to keep the new Batman script secret, insisting fans will have "so much more fun" not knowing any spoilers about the blockbuster.
The moviemaker went to extreme lengths to ensure the castmembers - including Christian Bale and Tom Hardy - were kept in the dark about the ending of The Dark Knight Rises, and even sent out scripts with pages missing.
Hathaway was closely monitored as she read scenes for her role as Catwoman, but she is adamant Nolan has the right idea about secrecy.
She tells Britain's The Sun, "I had to read the script in a locked room - Ok, maybe the room wasn't locked, I could be adding that for dramatic effect. But you know what I mean.
"I read it through once really fast and I went back and read over all of my scenes and tried to memorise them as much as I could instantly. It was cool. You could call Chris and ask, 'What is this scene about again?'
"When I screen-tested I took the sides (certain pages) home and it was really awkward, because the producer had to hunt me down to get them back so they could be destroyed."
She adds: "This should be treated with a certain amount of secrecy, which is great, because I think it is so much more fun to discover it in the movie theatre when there is so much anticipation about the movie."
