In the internet era, plenty of movies have gotten a sort of secondary fame by virtue of what you might call clip culture. One scene, or one joke, or even just one frame can go viral, independently of the movie that it's in. Everyone's seen that GIF of Chow Yun-fat giving a thumbs-up, but only a relative handful of people know it's from A Better Tomorrow II. There's a lot going on in Tobe Hooper's Lifeforce, but most horror fans only know of it because of Mathilda May's nudist vampire.
