Tenth Doctor David Tennant (Broadchurch, Harry Potter and the Goblet of Fire) is reunited with former companion Donna Noble (Catherine Tate, The Office) in this first set of adventures from the rebooted Doctor Who's fourth season. In these gripping stories, you'll meet the adorably cute but sinister Adipose, visit ancient Pompeii on the day before its infamous eruption, journey to the home world of the Ood, and more! Billie Piper and Kylie Minogue are among the guest stars that make this set of episodes more memorable than ever.
