10 Doctor Who Mistakes You Can NEVER Unsee
1. Matt Smith's Impossible Positioning (An Adventure In Space And Time)
No exaggeration: this is one of the most forehead-slappingly obvious screw-ups in the history of TV.
2013 biographical drama An Adventure In Space And Time tells the complicated true story of Doctor Who's origins. The story follows William Hartnell - brilliantly played by David Bradley - as he gets to grips with playing the First Doctor, and in an emotional final scene, Hartnell has a vision of the show's future success, which is personified by a cameo appearance from Matt Smith's Eleventh Doctor.
When Smith first appears, everything looks great: he's stood behind the TARDIS console, in the back layer of the shot, fiddling with the controls - as Doctors tend to do. But then, in the very next shot of Smith, he's magically moved positions, and is now stood in front of the TARDIS console.
What?!
It's clearly impossible for the Eleventh Doctor to be stood here (wouldn't he be right in Hartnell's face?), and quite how this slipped through to the final product is anyone's guess. It's such a huge screw-up at a pivotal moment in the story, and you'd think that the BBC would do anything it took to fix it. Guess not.
