關於影子問題好像只有這個...
The shadows change angles all over the movie. First the shadows appear right beneath the characters, then in the next clip they are cast with an angle. And the shadows that ships and computer-animated animals cast are different from the "real" characters.

下次再看「首部曲」時我再看看能不能抓出「瓊斯博士」，這片我只找到「丘巴卡」以及「ET」而已。
