If Hollywood has made anything abundantly clear over the years, it's that sex sells. Audiences love watching beautiful people being heroic and, inevitably, shedding their clothes for some cinematic rutting.
Sex scenes are pretty much pre-requisites in the horror, thriller and action genres, to the point that it's actually surprising when a movie doesn't feature them.
In the case of these 15 sex scenes, however, each came wildly out of left-field, emerging from nowhere either for comedic effect, to wake the snoozing audience up, or because the filmmakers had no idea what the hell they were doing.
These instances of cinematic lovemaking, ranging from weirdly earnest to shamelessly ridiculous, all caught audiences off-guard and as such left them either laughing, cringing or most anything other than turned on.
If nothing else, the scenes certainly do stick firmly in the mind, and in some instances even represent the best that the entire film had to offer (oh dear)...
15. Goebbels Going At It - Inglourious Basterds
Quentin Tarantino's never been one for subtlety, and in his marvellous war thriller Inglourious Basterds, he bamboozles the audience with a brief yet incredibly jarring - and intentionally so - sex scene.
When protagonist Shosanna (Mélanie Laurent) is first introduced to Joseph Goebbels (Sylvester Groth) and his interpreter Francesca Mondino (Julie Dreyfus), we smash-cut (ha!) to the pair going at it, doggy style with Goebbels squealing in ecstasy no less, for about three seconds.
It's acted, filmed and edited for maximum comedic effect, and works wonderfully. This wouldn't be the last time Q.T. sprang a surprise sex scene on audiences - remember the blowjob flashback from The Hateful Eight? - but it's certainly the most absurdly random one.
