DOCTOR Who star Matt Smith regenerates – into Bart Simpson as he fools
punters at America’s Comic-Con fair.
The hugely recognisable Time Lord actor managed to avoid being spotted by the
sci-fi fans as he browsed the stalls of the San Diego event.
He even checked out some of his own Doctor Who merchandise.
Matt also posed for pictures with fans as street-wise Bart from hit cartoon
The Simpsons.
