As I say, I believe this footage is genuine - Derren blogged about himself being on a bus last November, saying "Currently in the middle of filming on an open top bus around Oxford St under the Christmas lights (not pictured). Tried something I hope will pay off in a year or so. Could be quite exciting". Whether the numbers on the balls are genuine, however, I just don't know. Tricks of the camera and all that. But that's irrelevant. What I want to know is why it wasn't shown? This would have made the show brilliant instead of the anti-climax I felt it was. The natural assumption is that Derren and/or Channel 4 'lost their nerve', which of course makes you think he actually rigged the result. And no one is going to convince me that that is not seriously cool thing to believe. Or maybe they genuinely lost their nerve because he had rigged the lottery and showing the footage wouldn't have done him any favours if it resulted in an investigation. Or maybe it wasn't shown because he wanted those from the studio audience, who actually saw this footage, to write about it and keep the Derren Brown mystery rolling. He's good like that.
I hope the footage is shown at some stage though. Not just for my sake, or yours, but for Derren's. He looks a little bit stupid holding up a snowflake at the end of this trailer now. A snowflake that surely points to the footage shot under the Christmas lights. Or, as everyone else seems to believe, it just points to the frozen screen theory. (Which may have happened. Too).
