The BBC today confirmed reports -previewed in the new issue of Doctor Who Magazine - that David Tennant and Billie Piper will reprise their roles as the Doctor and Rose Tyler for November's anniversary special.
Despite many reported denials, the actors have long been rumoured to be making a return to the programme.
Tennant and Piper last appeared as the Tenth Doctor and Rose in The End of Time on New Year's Day, 2010.
The hour-long special - to be shown in 3D on TV and in cinemas - also stars yet another Harry Potter film actor, John Hurt (Alien, The Elephant Man, V for Vendetta, and Channel 4's new historical saga, Labyrinth), Ken Bones, Marshall Griffin, and newcomer Orlando James.
The celebratory story, scripted by showrunner Steven Moffat and directed by Nick Hurran, will commence production next week.
