Watch a demonstration of the visual effects work in Star Wars: The Force Awakens, but only if you’ve seen the movie, since there are plot points revealed here. I would suggest watching it in full-screen mode, since it's shown mostly in split screen.
The Force Awakens has been nominated for five Academy Awards, all in technical categories. The lack of pre-release viewing for critics may have contributed to the film receiving no major nominations for acting or directing, but it's up for Oscars in Film Editing, Sound Editing, Sound Mixing, Visual Effects, and Original Score. And deservedly so. Still, there's no guarantee of winning. Mad Max: Fury Road received ten nominations, in many of the same categories (plus Best Picture and Best Director), and the technical aspects of that movie were quite stunning. -via io9
Much apropos of nothing, here's the video link since the Vimeo version got taken down:
