Filming on David Tennant's finale as the Time Lord continues today on the streets of Cardiff with the return of Catherine Tate.

The award-winning actress played Donna Noble in the 2006 Christmas special, The Runaway Bride, and then returned (for the first time) in 2008's Partners In Crime and remained in the TARDIS throughout Series 4. Also spotted on set was Tate's onscreen grandfather, Bernard Cribbins, and mother, Jacqueline King.

Donna has become one of The Doctor's most beloved companions with Tate herself winning "Greatest Contribution" in the most recent end of year poll in Doctor Who Magazine. After this stint on the show, the actress will be shooting scenes for the new Jack Black film, Gulliver's Travels.

Outgoing showrunner, Russell T Davies, revealed in an interview with The Times that he will not be writing part of the finale - the post regeneration scene featuring Matt Smith. The writer said, "When he appears, every word will be written by Steven Moffat. He’s Steven’s, and Matt’s, character."
