Who's on You Tube?

David and Freema's video diaries now online.

The BBC has struck a deal with YouTube, the web's most popular video sharing website, to showcase a range of news and promotional material from its shows.

Always at the forefront of technology, Doctor Who is represented on the site by two exclusive video diary clips, filmed by the series' stars.

In the first, David Tennant reveals his new costume, whilst in the second, Freema Agyeman talks about the fun of her first day on set.
