10 Hilarious Doctor Who Mistakes You Definitely Didn't Notice

Partners in Crime is such a wonderful feelgood episode that its flaws are easy to overlook, although this one's quite a biggie, so it may bug you on rewatches.

Poor Donna Noble is thrown in at the deep end from the second she tracks down the Tenth Doctor, with Miss Foster and her gun-toting goons chasing the pair onto the roof of a building, forcing them to escape in a window-cleaning cradle.

This plan goes well at first, until Miss Foster uses her sonic device to destroy one of the cradle's cables. As you can see from the image above, this is the left cable when looking at the building, or the right cable from Foster's perspective.

However, that's not the cable she cuts, as can be seen a few seconds earlier, when she aims her sonic at the opposite side of the cradle.

This is one of the biggest continuity errors in modern Who, and you have to wonder if it could've been avoided by flipping certain shots, as was the case with Big Ben.

Hilariously, writer and then-showrunner Russell T Davies points this mistake out on the episode's commentary track, resulting in director James Strong feeling rather embarrassed. Dick move, Russell. Dick move.
