Doctor Who: Origins Movie

William Hartnell, the First Doctor

To celebrate the 50th anniversary of Doctor Who, BBC has commissioned a film to explore the origins of the series. Mark Gatiss, whose Doctor Who scripts include: "The Unquiet Dead," The Idiot's Lantern," and "Night Terrors," will write the script.

"An Adventure in Space and Time" will "tell the story of the genesis of Doctor Who," the BBC said. "Exploring all aspects of the longest-running science fiction series to date, the special one-off 90-minute drama will also look at the many personalities involved in bringing the series to life."

"This is the story of how an unlikely set of brilliant people created a true television original," Gatiss said. "And how an actor -- [original Doctor] William Hartnell -- stereotyped in hard-man roles became a hero to millions of children. I've wanted to tell this story for more years than I can remember! To make it happen for Doctor Who's 50th birthday is quite simply a dream come true."

No actors have been cast yet for the movie, nor has it been announced when it will air.

I'm excited for the film and to find out what else is planned for the 50th anniversary. Not many other television series have been on the air when their 50th anniversary has been celebrated. In fact, I can't think of any other right now.
