David Tennant was interviewed live on GMTV this morning at around 9:15pm about the upcoming Doctor Who episode The Waters of Mars. David confirmed on the show that the special, which is written by Phil Ford and Russell T Davies, will broadcast on Sunday the 15th of November on BBC One and in higher definition on BBC HD at 7:00pm. The Waters of Mars has been described as the start of the end for David Tennant's Tenth Doctor as he prepares to regenerate during the festive season. The Waters of Mars features David Tennant as The Doctor alongside Lindsay Duncan as Adelaide. In his interview David was also asked about his final regeneration scene, but wasn't letting any information out (why should he?). He was also asked about the possibility of a Doctor Who movie, but David said nothing is currently in the making. You can watch the GMTV interview here and remember to tune in to BBC One or BBC HD at 7:00pm on Sunday the 15th of November to catch The Waters of Mars. It will be the only episode broadcast since Easter's Planet of the Dead. The episode is around sixty minutes in length and will therefore finish at 8:00pm. It is thought that the programme will be followed by Confidential on BBC Three.
