Almost a year after it originally opened in theaters, the 3D version of "Star Wars: The Force Awakens" is racing towards its home release. The re-release of the film will include a number of never before seen deleted scenes as well as a commentary track from director J.J. Abrams. That commentary track will come with all sorts of insight into the making of the blockbuster "Star Wars" film -- and a new clip from the commentary revealed by io9 proves that there's still plenty about the film that fans don't know.

The new clip of commentary comes under the first scene between Supreme Leader Snoke and Kylo Ren. In his commentary, Abrams reveals that there's a secret bit of CG in the scene that goes by unnoticed -- and no, it's not the impossibly large Snoke.

"One thing I have to say: in this scene we originally shot Adam Driver with his mask off," said Abrams of Kylo Ren. "He had the first scene with Snoke with his mask off, and we ended up putting it on in post. So the mask is actually a CG mask. It was added later."

That's a pretty interesting revelation. Instead, the face of Ben Solo (a.k.a. Kylo Ren) is revealed much, much later during his interrogation scene with Rey (Daisy Ridley). It's interesting to learn that that reveal, which comes at a pivotal moment and so close to the film's end, was originally not intended to be as impactful as it initially was. As originally intended, Driver's face was set to appear way, way earlier in the film. The addition of a CG mask preserves that reveal until much later.

Abrams also spoke about how Andy Serkis got involved with the film as Snoke. "I was very lucky that Matt Reeves, one of my dearest friends was directing 'Dawn of the Planet of the Apes' and I got to see an early cut of the film with Andy Serkis playing Caesar but without any of the visual effects done," said Abrams. "Every 15 minutes there'd be a shot here and there, but it was the story in its entirety with human actors and I was blown away by Andy Serkis. And I met him and he was as lovely as they get, so I felt incredibly honored that we got to work together on this."
