LONDON (PA): Doctor Who is to be celebrated at the TV Bafta Awards this weekend to mark the programme’s 50th anniversary year. Stars Matt Smith and Jenna Louise Coleman have filmed a special sketch to be screened during the ceremony on Sunday and a pair of daleks will be trundling up the red carpet beforehand. The announcement of the celebration for the family show comes as it was reported veteran actor John Hurt will feature as a previously unknown incarnation of the Doctor in a special episode later this year.
