Doctor Who fans will get a double treat this spring: not only is the SCI-FI Channel premiering the fourth season of the long-running sci-fi dramedy, but launching its new spin-off, The Sarah Jane Adventures, as well.
Come April, David Tennant will once again give life to the tenth timelord of Doctor Who, but this time, with a new companion. Comedienne-actress Catherine Tate will reprise her role as Donna Noble, the runaway bride from the previous season's Christmas episode. The doctor's former companion, Martha Jones, played by Freema Agyeman, will return in the middle of the season.
