Two Doctor Who specials will reportedly be filmed in America in 2009.
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 showrunner Russell T. Davies, who will depart his post before the fifth season in 2010, "is determined to go out with a bang and the specials will be explosive - we’re spending much more money on them than normal".
