It's happened before, and once again rumors are rolling about a potential big-screen adaptation of Doctor Who, this time helmed by director David Yates (Harry Potter).
As usual, a ton of names have been thrown out as to who might play a feature film incarnation of the Doctor. Radio Times has suggested people from Hugh Laurie, Colin Firth, and Ricky Gervais, to incredibly odd choices such as William Shatner, Lady Gaga, and even Justin Bieber.
As usual, these are just rumors (thankfully). Personally I've never been keen on a movie adaptation of Doctor Who. The two Dalek movies of the 60s starring Peter Cushing were more than enough for me. Doctor Who works best at the level its at, as a TV series with an already expansive mythology, and room enough to continue to grow and expand that mythos. And knowing Hollywood these days and their propensity to butcher our childhoods, I never ever want them to get their hands on it.
