When Gwyneth Paltrow is on Albert Bridge (the one with the light bulbs) she says, "My grandfather built this bridge." Well, he must have been an old goer to have such a young grandaughter - the bridge was built in 1874 - she means her great grandfather.
I am sorry but this is completely wrong, you need to go watch it again. For starters she is not standing on the bridge when whe makes the comment, she is in a boat with James and the bridge is behind them. And she does say great-grandfather quite clearly. The exact comment is and I quote "I love this bridge, my great-grandfather helped build it."
