I don't spend all my time in the internet.
It's only when a particular movie intrigues me because somebody looks familiar that I use the internet to check things out. Or in the case of Atonement, because of the rabid, unhinged sex appeal of that green dress. Or the bra the actress was wearing in the last Indiana Jones movie - I needed to find out who she was. Otherwise I just watch the movie and that's that. Unless they wear a special dress, or a special bra, I can go blissfully through life not having a clue about who Kiera Knightley or Kate Blanchett is.
But now I can see I'm not as clued in as some of the others here.
BUT to be fair, I looked in here FIRST about Momma Mia, and nobody had commented on it's connection to James Bond. And to be TOTALLY fair, that's a good indication that nobody had noticed it.
