Revealing mistake: Just after Rey catches BB-8, she looks back at the sand worm. Suddenly, in this shot, you can see the rigging seam on its neck where it connects to the upper part of the mouth, which is not visible in other shots. Usually, the neck seam blends in or is not visible, but in this shot, you can see where the neck and top of the mouth are separate pieces in this 2D rig. (00:01:59)
BB-8 Bandits - S1-E2
Revealing mistake: When Rey is speeding across the desert away from Teedo and his gang, the shot of her on her speeder has BB-8 not casting a shadow on the side. In most other shots, the shadow of the speeder has a "bump" on the side where BB-8 is tied to it, except in that shot and a few others. (00:01:07)
