The news comes from the Daily Express, who quotes an unnamed Who insider as saying, “It will be fitting to have Tom back to mark the 50 years. He was a big part of the show’s success and is much-loved by the fans.” Naturally, sources both official and unofficial are keeping mum about the nature of Baker’s appearance. Will he be playing the Fourth Doctor? If so, how will they explain the fact that he’s, well, three decades older? He could just be playing an entirely different character, but I’m sure the fans would love to see him return in the role that made him famous, and which some fans still consider the quintessential Doctor. Of course, this is Doctor Who, so I’m sure they can come up with some sort of technobabblish explanation for his current appearance if they so wish.
