Audio problem: Right before Kylo Ren kills Lor San Tekka, he says "You're so right," and the sound of him igniting his lightsaber while raising it upward, then killing Tekka. You can see red light that is flickering at the bottom of the screen while Ren is talking, meaning that the lightsaber is on, but there is no sound of the lightsaber, and there is still a sound of ignition when it is already on.

Revealing mistake: After Poe's X-Wing is destroyed, when BB-8 leaves the village and rolls off note all the distinctive hills and sand dunes in front of BB-8. Later, when Rey hears BB-8 with Teedo and she rushes off note the sand dunes in front of her, but after she rescues BB-8 and walks in the opposite direction those same sand dunes are now in front of them, which were also the same sand dunes in front of BB-8 when he left the village the night before.
Question: Was there a specific reason Mark Hamill got 2nd billing (other than he's Luke Skywalker)? Was the billing order based on how much they each got paid? I don't recall seeing his picture on any The Force Awakens posters and it didn't seem like they needed to add hype to the movie by billing "big name" celebrities. Of course that leads to asking why Hamill reportedly got paid 7 figures for his "role" when the actual stars got less than half or a third of that. I know they're all in unions, so is it a union thing? Or just a better agent thing?
Chosen answer: The actors playing Rey, Finn, Poe, and Kylo Ren were mostly unknown, while Mark Hamill is famous worldwide as both a screen actor and voice actor. The billing order was likely based on their fame and then on their new roles. It's not a union thing, minimum wage in the Screen Actor's Guild is far lower than what they were paid. It's a combination of bigger star, better agent, and the future of the series.





Suggested correction: BB-8 is heading towards a background at night, the other instances are all near where BB-8 is since they are all focused around him. Rey finds BB-8, only possible if she is near the same background. BB-8 was going towards that background so can only be closer to it than before. Same goes for Finn as they crashed near where BB-8 was, since they were looking for him. They are not the exact same locations but a couple of miles apart, which produces the same background.

When Rey rushes toward Teedo and then when she walks away in the *opposite* direction with BB-8 the very same sand dunes are still in front of her and BB-8. Those sand dunes are also the exact same sand dunes right in front of BB-8 when he left the village. The correction states "They are not the exact same locations but a couple of miles apart," but they are in fact the exact same sand dunes and hills, certainly not miles apart, and I do not mean the general horizon "which produces the same background" (screenshots available now). The filming of these scenes was done at the same location.
