What's the sexiest science fiction or fantasy movie of all time?S

Escapism is sexy. There's something beguiling and enticing about the idea of stepping into other worlds and having larger-than-life adventures. So it's no surprise that so many science fiction and fantasy movies are hella sexy. But which is the sexiest?

Please post a picture or clip of your pick for the sexiest science fiction or fantasy movie of all time. PLEASE KEEP THIS WORK-SAFE. And please mention the title, and why it's so sexy. Thanks!
