Here's our very first look at comedienne/ actress Catherine Tate in DOCTOR WHO. Tate joins the show for David Tennant's third season as the doctor. The BAFTA nominee reprises her role as Donna Noble from the 2006 Christmas special.

The fourth season of the series sees the doctor meeting legendary murder mystery novelist Agatha Christie as well as one of the show's most popular aliens, The Ood. The series is set to hit BBC1 in 2008, though a Christmas special is currently in production, which sees the doctor and guest star Kylie Minogue aboard the doomed Titanic. The special is set to air Christmas Day.
