Man of Tai Chi

Factual error: After the scene where Karen Mok is standing in the empty fighting arena, there is a cut to the city night skyline, with the Moon rising fast as time is fast forwarded. However, all the stars remain stationary... Which is nonsense, because the Moon is revolving around Earth much slower than Earth's own rotation. The Moon's (and the Sun's, obviously) rising and setting is because of the latter, that's why the stars should also be moving along with the Moon.
