'Who' producer hints at return of The Master

Doctor Who producer Julie Gardner has suggested that John Simm's incarnation of The Master may return, despite the character's on-screen death.In an interview with iF Magazine, Gardner said: "It would be rude not to [leave the door open]. He’s a great character. John Simm is amazing and I would go to work every day with him. His scenes were so much fun to do."Life On Mars star Simm played The Doctor's ultimate foe in the final three episodes of the third season and was killed during the finale, his body burnt to a crisp. However, a female hand was seen reaching into the ashes and collecting the ring that The Master wore.
