But now there are apparently serious reports that the last of David Tennant's string of 2009 specials as the Tenth Doctor, prior to making way for a new actor in the role, might be done as a musical.
"Doctor Who, the musical has been mentioned," Tennant told reporters recently. "I would be up for it. I love a song and dance." Reportedly keen on the idea are outgoing executive producer Russell T. Davies, who wants to exit "with a bang," and Barrowman, whose spun-off character Captain Jack Harkness recurs regularly on Doctor Who.
Other likely names for a musical episode include ex-companion Billie Piper, who was a pop singer before she turned to acting, and (less likely) Australian pop star Kylie Minogue, who appeared as Astrid in last year's Christmas special (though she died at the end of that, not that that would stop them).
It's said that Davies loves classic Hollywood musicals, especially Doris Day's Calamity Jane. He's also known to be a fan of shows like Buffy The Vampire Slayer, which wowed fans with a big musical episode, "Once More, With Feeling" (6x07, in Nov. 2001).
Keep in mind the whole thing could be a wind-up – with Tennant and Davies it's tough to know what to believe, and the press love to seize on any random thing either of them happens to say. Tennant, for example, is telling everyone the Eleventh Doctor will be James Nesbitt, and while Nesbitt is apparently a contender one gets the feeling that he's doing this mainly to tweak his friends and the fans. No announcement has been made, or is expected in the near future.
