Two new Doctor Who specials will reportedly be filmed on location in America next year.

The News of the World quotes a BBC insider as saying: “Doctor Who already has a huge following in the States. It’s on the Sci Fi Channel and is watched by millions of people there every week.

“But two specials in America, with a US setting and a US assistant, will take it to another level. David Tennant is already gaining a huge following and this will make him really hot property.”

The source added that show boss, Russell T Davies, who is due to leave the show before its fifth series “is determined to go out with a bang and the specials will be explosive - we’re spending much more money on them than normal”.
