We are now towards the end of our California trip; the last part of which has been spent in San Francisco.

The City is beautiful and we are in the heart of town in Union Square. It feels very Christmassy too – a giant Macy’s Christmas tree overlooks an outdoor ice skating rink and there are beautiful lights everywhere.

Tomorrow, just before we fly home, we have the extreme honour of visiting Walter Murch at his home. He has generously offered to spend the first morning of his Christmas holiday with us, so that we can interview him about the time he directed Return to Oz for Disney at Elstree Studios.

I love the film and feel Walter should have been given a chance to do a director’s commentary on the DVD release, so I hope our interview answers some questions about the making of the film.
