2001, Stanley Kubrick's seminal space odyssey started it all off, positing that Jupiter's moon Europa is a second testbed for the organic exercise that caused Homo Sapiens here on Earth.
Avatar, James Cameron's Fern Gully re-imagining, featured a moon called Pandora that was shown to orbit a planet that looked very much like a blue-filtered version of Jupiter replete with big all-seeing-eye persistent weather spot.
Prometheus, title of the forthcoming Ridley Scott film, is actually an object orbiting within the Saturnian ringspace. And what do we see in the back-right of this Prometheus-has-landed image? Saturn's rings, right?
In fact, Pandora is the name of another of Saturn's shepherd moon system, as it's called, that keeps the dirty-ice-particle rings where they are.
What's going on, Holywood? Spill your guts.
