Did anyone notice...
After Sylvie drops Jasmine off at Dexter's house, then goes back to the car with her new family, you hear a voice (her husband?) saying something like "Come on Moriarty" (it may not be that exactly, but definitely "Moriarty").
So Sylvie named her next child Moriarty, after the parlour game - pretty funny. I don't remember that detail in the book.
BTW I read the book last year and was prepared to be disappointed by the film, but I loved it. (Although Anne Hathaway's accent was a bit of a distraction at first, it's true - she didn't have it for the first scenes in Edinburgh, and then suddenly when she moves to London she sounds like someone out of Coronation Street! Then it kept appearing, disappearing and moving between London, Yorkshire, Manchester and America.)
The ageing make-up was done well too, I thought, especially on Jim Sturgess. (Though I hope I don't age quite as much in 5 years as he did from 2006 to 2011!)
