Addition to film locations

Der John,
Yes, love the site as I've always been intrestd in film (and television) locations. In "The Lavender Hill Mob" there is a scene where a car is being chased (I think) around a tree in the middle of the road. The tree is still there at the junction of Carlton Road and Castlebar Road, Ealing W5. There is a further recognisable Ealing scene, but I would need to see the film again before I could identify it (I think it's a house in The Avenue, West Ealing?).
Best wishes,
Patrick
