10 Most Bizarre Doctor Who Moments

10. Toilet-Trained Gorilla (The God Complex)

The God Complex is a genuinely unsettling episode of Doctor Who. Clearly inspired by Kubrick's The Shining, it's a trippy affair set within a labyrinthine hotel, with strange, spooky imagery lurking round every corner - and hiding in every room.

We see laughing puppets, sad clowns, Weeping Angels, and even overly-stern parents, all representing the primary fears of the story's core cast. Most of these fears are effectively portrayed, but one that doesn't fare so well is this laughable "gorilla", which attacks Lucy Hayward during the pre-title sequence.

Now sure, the BBC didn't have the budget to call in Andy Serkis for a bit of mo-cap, but we have to wonder... was this thing supposed to look so fake? Or did the crew genuinely think "yep, nailed it - that totally looks convincing!"

Either way, this bizarre sight completely destroys the tension of the scene - as does the unusual choice to add a "toilet flushing" sound effect as the gorilla lumbers out of the bathroom. It's a highly cringey moment in an episode that, again, is otherwise very effective in conveying the twisted fear of the hotel.
