10 Hilarious Doctor Who Mistakes You Definitely Didn't Notice

One of the great things about Doctor Who is that it doesn't over-rely on CGI. Many of the show's monsters and environments are digital, sure, but many more of them are done practically, and it's tough to beat the immersion of a convincingly-done alien mask, or a scene that's clearly shot on location (usually in a quarry).

At the same time though, a lot of the show's CGI is also very well done, especially in recent years. Even some older stuff - like those stunning shots of the sun in Series 3's 42 - still holds up today. However, in Series 4's Midnight, the CGI couldn't even be bothered showing up, let alone presenting itself in a suitable manner.

Right before the title sequence kicks in, the Tenth Doctor tries (and fails) to convince Donna to join him on his tour of the titular planet. As he hangs up the phone, the camera pushes in, and behind him, a huge chunk of green screen is visible for a good couple of seconds. Clearly, someone forgot to key it out.

It's one of those "how did I miss that?!" mistakes you'll never be able to unsee (this particular writer only spotted it during a 2020 rewatch), adding a funny distraction to what was supposed to be an ominous end to this cold open.
