Trivia: Nine-one-one (written "911") is used exclusively for the emergency telephone number in the U.S. (Nine-eleven might be used more often in England.) In the case of "nine-eleven", a slash is used to show the separation of the numbers (9/11), which then dictates its pronunciation and distinguishes it (date of terrorist attacks) from the emergency 9-1-1 number.
Trivia: Before production began, Judi Dench was still suffering from a toe injury she obtained whilst working on her previous movie. She didn't tell anyone about the injury as she didn't want to lose her role.
