Gillian Anderson as The Rani?

Various different sources are reporting that Gillian Anderson, the actress who is well known for her role in The X-Files, will be appearing in Doctor Who Series 5 as the Rani. The Rani is a Time Lady who is an old enemy of the Doctor and she was originally played by Kate O' Mara in the classic series of the show. A BBC insider apparently said: "Gillian obviously has a massive sci-fi following and it's felt that it would be a major coup to have her appear in Doctor Who. The team behind the show are keen for the next Doctor to have lots of new enemies and Gillian would be a glamorous and impressive addition to the list. The Rani would be a perfect role for her as the character used to be regarded as one of the Doctor's most deadly opponents. It should be noted that at the moment the BBC have not confirmed any of this information so it may or may not be true.
