Doctor Who is looking toga-tastic as the Time Lord hurtles back to the Roman Empire in the fourth series.

The Doctor arrives in Pompeii with his new assistant, Donna, the night before the famous Mount Vesuvius volcano erupts - but should they warn everyone?

You'll have to wait and see, but TV insiders promise the episode is one of The Doctor's most adventurous yet.

Filming has been taking place in Rome in studios that were transformed to recreate the ancient city of Pompeii.
