Pick up a pile of publicity

The BBC billed its "staggering" April Fools' film of flying penguins as coming from a new natural history series. And now, like Planet Earth before it, the spoof has its very own behind-the-scenes accompaniment in which producers explain just how they managed to trick many a viewer. The original film, now being used as a trailer for the BBC iPlayer, has already zoomed to the top of the iPlayer chart. Who says a bit of TV fakery can't have a positive outcome?
