Harry Potter filming locations seems to be turning into a major tourist industry. This is the first of the Potter movies that doesn't feel like it's entirely a kids' movie, thanks largely to director Alfonso Cuaron, who brings a more sombre tone.

The scenery seems a tad more specrtacular, too. Where did those mountains come from? Hagrid's hut, which started out on the safe, flat fringes of Black Park is now perched on a steep hillside. But I guess that's magic, huh? The Hogwarts locations, this time around, filmed in Scotland (the Glenfinnan Viaduct has already been seen in the earlier movies).

There are some locations in and around London. After fleeing Privet Drive, Harry is picked up by the Knight Bus on a brand-spanking new housing estate opposite the Leavesden Studio in Hertfordshire.

The bus, thoguh, careeers wildly along Green Lanes, in Palmers Green, North London, on. The Leaky Cauldron seems to have undergone a bit of a change.

In ...the Philosopher's Stone, it could be found in Leadenhall Market, at the foot of the Lloyds Building in the City. The new Cauldron stands beneath the railway bridge on Stoney Street opposite Borough Market. This is a popular area for filming. Here you can find locations for Bridget Jones's Diary, Lock, S tock and Two Smoking Barrels, The French Lieutenant's Woman, Howards End and Entrapment, among others. Check it out fast. The streets here are under threat of redevelopment.
