Canadian fans out there can watch the full uncut final episode Journey's End on the CBC's Doctor Who site. Hurry up though since it's only available for the next few weeks due to the CBC license agreement with the BBC. 19 minutes were cut to make the episode fit the 44 minute slot.
DWIN has complied a list of the most blaring omissions to the CBC broadcast if you don't have the time (or bandwidth) to view the full episode.
UK media is speculating if David Morrissey will be the next actor to play the Doctor since David Tennant has said he will be leaving the series. I personally doubt it but I can see the special's plot following the Big Finish 2001 story The One Doctor. It wouldn't be the first time that the current series has borrowed from Big Finish. Rob Shearman reworked themes from his Big Finish story Jubilee into the episode Dalek. And Marc Platt's Spare Parts inspired Rise of the Cybermen & The Age of Steel.
