Double dose of Doctor Who in 2011

Doctor Who fans are in for a treat with two series of the hit show set to screen in 2011.

Speaking at the International Television Festival in Edinburgh, producer Steven Moffat confirmed that a seven-episode series would be shown around Easter, followed by six episodes later in the year.

And he promised that there would be an "earth-shattering" cliffhanger midway through the two.

Moffat added that the Doctor, played by Matt Smith, and his sidekick Amy Pond - aka actress Karen Gillan - would face a "game-changing" moment in the new series.

Looking at the next series I thought what this show needs is a big event in the middle," he said. "I kept referring to a mid-season finale.

"So we are going to make it two series – seven episodes at Easter building to an earth-shattering climax, a cliffhanger we could never normally do because it would be too long before it came back. An enormous game-changing cliffhanger that will change everything."
