At the end of the film, after the Death Star is destroyed, there is galaxy-wide celebration. In one of these sequences, there is a bridge (on Coruscant maybe) that a small ship from the background is supposed to fly UNDER. The ship does fly in from the background but if you notice, the bridge was not masked out and the ship is momentarily ON TOP of the bridge. Based on its size (getting bigger as it gets closer), it was clearly meant to go UNDER the bridge, NOT OVER IT. Two things I can't believe... 1)The geeks at ILM never caught this... and 2)None of you ever caught it!!! Geeze, come on!
