In an interview in The Sun today, Freema Agyeman comes clean on a very important subject: "I'm a big sci-fi fan - I even went to a couple of Star Trek fan conventions. The Next Generation was my favourite show and I loved Patrick Stewart as Captain Jean-Luc Picard."
Agyeman says that she grew up with Doctor Who when Sylvester McCoy was in the title role, but even then she was more of a Trekkie. However, she comments "Now I can't wait to go to a Doctor Who convention as a member of the cast."
This is partly to do with the reception that she's gotten from Doctor Who fans: "The fans have been really, really encouraging. I've had some great letters saying that they'll miss Rose but they're looking forward to meeting Martha. It warms my heart to know that the fans are backing me."
Catch Agyeman's debut as Martha Jones this Saturday, 31 March, at 7 pm in "Smith and Jones", the first episode of Series Three.
