"Arriving in Pompeii marks the start of another exciting adventure for the Doctor and Donna," said Doctor Who's Executive Producer and Head Writer, Russell T Davies. "Donna is stunned to find herself in the midst of history's most famous volcanic eruption. Viewers can expect many more ambitious storylines and a whole host of guest stars in 2008."
Peter Capaldi is to guest star as Caecillius. He's joined by Quadrophenia and Rose and Maloney actor Phil Davis as Lucius. Also guest starring will be Tracey Childs, who plays Metella. The filming of the episode took place at Cinecitta studios in Rome, which the Doctor Who team expertly transformed into Pompeii for a week of filming in September of this year.
