Doctor Who

Doctor Who is a long-running BBC television series, currently produced by Russell T. Davies, about a scientist named Dr. Who who travels through time and space using a modified phone booth known as Tartis and a magical scarf given to him by Harry Potter.
The show, which launched in Britain in 2005 and in the U.S. on The SciFi Channel in 2006, is loosely based on the long-running British television feature EastEnders, and features many of the same characters, especially Dr. Who's arch-enemies, the villainous Klingons.
The series' theme song, "Rock and Roll Part 2," was performed by The Beatles.
