I... I have a problem. I can't stop researching George Lucas' Episode VII. Save me ERA.
I watched the documentary from The Force Awakens Blu-ray last night and was intrigued by an art department review it showed from February 6th, 2013, just after George had turned over the project to J.J. There were big art boards behind everyone with stills from previous movies and concept art. One board was labeled "Act 2" and appears to be comprised of nothing but existing stills and art, including Darth Talon.
The piece just above Doug Chiang's head here is actually one of Ralph McQuarrie's first concepts for Darth Vader's castle in Empire Strikes Back.
I point this out because there was an original piece of concept art for Vader's castle made for
The Force Awakens the month this meeting took place:
Then there was an entire concept art board for Felucia with every piece we can see incorporating a canyon, including a piece that was included in
The Art of The Force Awakens titled "Felucia Canyon" that can be seen in the middle of the screenshot.
That piece as shown in the art book includes a male figure with a red lightsaber looking down on the Millennium Falcon.
