I have. I would definitely recommend watching the film first, before reading the story. The film is great. It adds a little side-plot to make it work better as a film, but it doesn't properly explain the core physical idea behind the short story (honestly, I can't imagine how it could, the story almost assumes its readers have some physics background, though it does try to explain). Having read the story first, I almost found the film a little boring, which is such a shame because it's a truly beautifully shot, well-executed film. I suspect I'll enjoy it a lot more watching it a second time...
