Today I visited the London Science Museum to see the LOTR exhibition, when none other than Sir Ian McKellen turned up to be shown around the exhibits by (who I presume to be) the curator, and in tow was a camera crew and various production people and museum staff. Sir Ian was discussing the exhibits on camera and when he got to the Gandalf display they handed him his staff so he could wave it around for us. He spent some time talking to the museum visitors (many of whom amazingly had failed to realise who he was when he first arrived!), and signed autographs.
The camera crew were filming a program called The South Bank Show; no-one seemed sure of the dates that it would be aired but it is presumably being made for the run up to ROTK. [More]
