Says the press release:
Following on from the phenomenal success of the first two series that have taken British television by storm, the third installment of Doctor Who is full of new thrills, new laughs, new heartbreak and some terrifying new monsters. From the moment the Doctor (David Tennant) walks into the life of medical student Martha Jones (Freema Agyeman) he changes it forever. Together they find themselves travelling through time and space encountering extraordinary events, amazing worlds and faces both old and new. They come face to face with the ruthless Judoon, a vicious plasmavore and the Doctor's sworn enemies, the Daleks, who have been hiding in 1930s New York with a terrifying plan for humanity.
Strangely, BBC Entertainment's home page features David Tennant and Catherine Tate!
