Our friends at The Star Wars Report alert us to this fascinating news from J. J. Abrams regarding a CGI effect in The Force Awakens, that escaped our attention.
J.J. Abrams points out in this exclusive clip from his new Force Awakens commentary track.
The clip [take the source link below], making its debut on io9, comes from one of the first encounters we see between Snoke and Kylo Ren in The Force Awakens.
…the most interesting tidbit Abrams reveals that this scene was almost the very first moment we saw the young man underneath Kylo Ren’s mask—a moment saved in the film for later, during his interrogation of Rey, which becomes a pivotal moment in Kylo Ren’s emotional journey. After Abrams decided to save the reveal, instead of reshooting Adam Driver’s part of the sequence, ILM simply inserted a CG replica of Ren’s mask to layer over Driver’s performance. It’s a small thing, but it’s incredibly effective, because it’s completely impossible to tell—and it makes Kylo Ren’s eventual unmasking much more powerful.
