Who rewrite after damage to bus

The Doctor's bus takes an unexpected detour during the episode

Doctor Who writers were forced to change the script for the show's Easter special after a double-decker bus was damaged ahead of filming in Dubai.

Planet of the Dead's plot sends David Tennant's Doctor and guest star Michelle Ryan on a dangerous bus trip.

One bus is being used for filming scenes in Cardiff, but the top deck of the second vehicle was damaged as it arrived in Dubai.

A spokeswoman said that shooting was "continuing as normal".

'Huge impact'

Parts of the script by executive producer Russell T Davies and co-writer Gareth Roberts had to be changed as a result of the damage.

Planet of the Dead is the first of four Doctor Who specials, which will bring to an end David Tennant's spell as the Time Lord.

Ex-EastEnder and Bionic Woman Ryan plays Lady Christina de Souza, a woman with a mysterious past who Davies says will have a "huge impact" on the Doctor.

Comedian Lee Evans is also on board for the episode but further details of the plot are being kept secret.
