Continuity mistake: When we first meet Rey, she is scavenging Imperial wreckage, and she slides down the sand dune on a makeshift sled (she left her speeder at the base of the sand dune, which means she trudged up that massive dune). When she reaches the bottom of the dune, her speeder is casting a distinct, dark shadow on the sand. As she fires it up and rides away, the speeder suddenly casts no distinct shadow on the sand, even after she reaches her destination and parks it. (00:12:00)

Factual error: In the opening sequence, the camera pans down on a planet and moon that are three-quarters lit in sunlight (with the sun being far off-camera to the left). A battlecruiser then crosses the images as a silhouette, eclipsing the planet and moon in total blackness. Impossible. The battlecruiser should have been lit three-quarters in sunlight, same as the planet and the moon. Stranger yet, as the stormtrooper shuttles are deployed and cross over the battlecruiser silhouette, the shuttles are illuminated. (00:01:55)
