Doctor Who: 10 Superfans Who Landed Starring Roles

You might be thinking that being cast as the Doctor's trained mirror image super villain, The Master, would be actor Sacha Dhawan's first step into the Whovian spotlight. Well, you're wrong.

In 2013 to celebrate the 50th anniversary of Doctor Who the BBC commissioned a brand new docu-drama, depicting how Doctor Who was created. It was written by Mark Gatiss and stared David Bradley as William Hartnell, who would later go on to star in the main show as the First Doctor alongside Mark Gatiss.

Also starring in the drama was current Master, Sacha Dhawan, playing the loveable Waris Hussein, a British-Indian television director.

"I never expected in a million years that in a few years time I would be playing the Master. So yeah it's brilliant. In a way by being a part of An Adventure In Space And Time history had already of been written but I guess with this I was writing my own history and that was pretty exciting but really nerve-racking as well."
