Star Wars: The Force Awakens looked great. There's no denying that. After a prequel trilogy that sucked the life out of actors' performances due to the overuse of green screen CGI effects, director J.J. Abrams' decision to use more practical effects in the new sequel resulted in a film that was far more tangible and exciting.
However, that's not to say he used no computer generated effects. Far from it in fact; the below video (put together as the film enters the Oscars race for its special effects virtuosity) reveals that even the most believable of sets – including those built physically – had a computer-aided touch up.
That shouldn't come as a surprise, nor should it feel like a betrayal on the behalf of the film makers who promised a return to puppetry and model making. To make such an other-worldly science fiction film on this scale even remotely believable requires many different art departments to work together in harmony. And, as the clip shows, The Force Awakens works so well because it's use of computer generated imagery is used to complement practical effects work, rather than all-out replace it.
