JJ reveals what footage was cut from Rey's "Forceback" when she picked up the lightsaber
(@ 1:54)
Touching the lightsaber triggers what we call the 'Forceback.' There were many iterations of this. In one, from the Cloud City Corridor, she looked down and saw Vader fighting Luke, which we ended up cutting. We wanted it to be a more personal story, something that she couldn’t comprehend, that was overwhelming to her, frightening to her, that was taking her through all of these elemental experiences, of fire, of rain, snow, wind. But also that she was being confronted with truths about the Force, about the past. The Knights of Ren here, the past for herself. She realizes that the cries she heard were actually her own cries as a young girl being taken away from her family. And then she hears a voice, 'Rey,' and that’s Obi-Wan Kenobi.
