NEW YORK - February 4, 2008 - SCI FI Channel has acquired the fourth season of "Doctor Who" and the phenomenally popular series' new spin-off "The Sarah Jane Adventures" from BBC Worldwide America. Both series are slated to premier on SCI FI in April 2008.

"The Sarah Jane Adventures" is written and produced by the same creative team behind "Doctor Who." Having traveled the universe with The Doctor, Sarah Jane is used to alien encounters. Accompanied by her new young friends Maria, Luke and Clyde, she becomes embroiled in an offbeat world of mystery and danger.

In season four of "Doctor Who," David Tennant reprises his role as the tenth Timelord. For his latest adventures he is joined by a brand new companion, Donna Noble, played by Catherine Tate who appeared as 'the runaway bride' in the previous season. 'Martha Jones,' played by Freema Agyeman, the Doctor's most recent companion, who had a dramatic role last season's finale, makes a triumphant return in the middle of season four.
