If you're ever in London, don't ring the bell on a bus like Tom - you'll really upset the driver. And don't bother looking for Chelsea Library, you've as much chance of finding it as... the Holy Grail ...or anything remotely moving or illuminating or even fun in this very dreary two and a half hours. Now there are some things that look good in the movie: the Louvre pyramid at night, Audrey Tatou when she smiles (although she spends a lot of time sitting down looking shocked), the chapel at Roslin in Scotland, Ian McKellen camping it up, London around the Temple Church. And some things that look very bad, chief among them Tom's haircut. If you're ever in London, get a decent haircut before you land - you'll really upset the Fashion Police.
