As Hollywood continues to push the envelope on sex scenes, you'd think there were very few ways to get a shock out of audiences when it came to the increasingly public act of love-making.
If you saw The Untamed this year, you'll know that is entirely inaccurate, as the Mexican film torpedoed one of the final remaining taboos of "mainstream" cinema with sex scenes between a human woman and a tentacle monster. It's a particularly arty film and there's not masses of exploitative shots, but when the frank, disturbing (but weirdly sensual) scenes are captured in unblinking focus, it's stunningly memorable.
And it's definitely one of those movie images that will burn itself into your psyche, even ignoring how much it demands to be paused.
