A parody of the original series, it starts off with the Doctor played by Rowan Atkinson and his assistant Emma (played by Julia Sawalha) meeting the Master (played by Jonathan Pryce) on the planet Tersurus. During the course of the series, the doctor is forced to regenerate several times, turning into (in order) Richard E. Grant (the conceited Doctor), Jim Broadbent, (the shy Doctor) Hugh Grant (the good-looking Doctor) and Joanna Lumley. The series ends with the Master and the (newly-female) Doctor taking off together.
The script was written by Steven Moffat, the producer was Sue Vertue and the director was John Henderson.
