Who Facts;
For The 2006 Christmas Special ‘The Runaway Bride’ the Doctor Who Production Team had to produce special banknotes to conform to strict Bank of England guidelines for the use of fake banknotes on TV. They came up with the ‘10 Satsumas’ featuring the 10th Doctor, and one is on display at the British Museum in London.
