The new Who movie will not be related to the TV series in any way as Yates tells Variety:
"Russell T. Davies and then Steven Moffat have done their own transformations, which were fantastic, but we have to put that aside and start from scratch."
"We're looking at writers now. We're going to spend two to three years to get it right."
"It needs quite a radical transformation to take it into the bigger arena."
Yates has begun developing the Doctor Who movie with Jane Tranter, BBC Worldwide's L.A.-based exec VP of programming and production, and does not rule out an American writer much as Harry Potter had Steve Kloves.
"We want a British sensibility, but having said that, Steve Kloves wrote the Potter films and captured that British sensibility perfectly, so we are looking at American writers too."
