Billie & David to Reunite?

From Now Magazine:
Doctor Who stars Billie Piper and David Tennant are being lined-up to appear in a new movie together.
The pair are in talks to reunite on screen in the London-based thriller Love On The Murder Mile.
Billie’s husband Laurence Fox, 31, will be behind the camera and his brother Robin will produce.
‘Laurence always had this ambition to direct,’ he tells the Daily Mail.
Brothers & Sisters hunk Matthew Rhys and comedian Mackenzie Crook are also in negotiations for roles.
The Secret Diary Of A Call Girl star Billie, 27, quit the part of Doctor Who assistant Rose Tyler in 2006.
David, 38, was replaced by Matt Smith, 27, as the Time Lord on New Year’s Day.
