Crisis on Earth-X, Part 2 - S6-E8
Deliberate mistake: During the big battle, Arrow is knocked down and when he opens his eyes, the reflection in his eyes is tilted over to give the sense he's seeing things sideways. But the reflection should still have shown the proper orientation no matter what orientation his eye was at. Think of looking into a mirror and then rotating the mirror to the side, the reflection wouldn't rotate.
Chosen answer: There is no evidence at this point to suggest that this is the case. Most indications at this point suggest that Green Arrow is not under consideration as a likely character for any proposed Justice League movie.
