Ferdinand, a little bull, prefers sitting quietly under a cork tree just smelling the flowers versus jumping around, snorting, and butting heads with other bulls. As Ferdinand grows big and strong, his temperament remains mellow, but one day five men come to choose the "biggest, fastest, roughest bull" for the bullfights in Madrid and Ferdinand is mistakenly chosen. Based on the classic 1936 children's book by Munro Leaf.

When the hospital she works at is transported to the moon, medical student Martha Jones joins forces with The Doctor to hunt down an alien fugitive before the oxygen runs out

This is the first series to feature David Tennant as the tenth Doctor. He continues to travel with his companion Rose Tyler (Billie Piper), with whom he has grown increasingly attached. They also briefly travel with Rose's boyfriend Mickey Smith (Noel Clarke), and Camille Coduri reprises her role as Rose's mother Jackie. The series is connected by a loose story arc consisting of the recurring word "Torchwood". This is also the first series to be preceded by a Christmas special, which was commissioned to see how well the show could do at Christmas. The success of "The Christmas Invasion" led to the Christmas special becoming an annual tradition.
