Factual error: After Oro Dassyne has boasted about his fortress' defenses and the droid standung by him announces that he has spotted two Jedi approaching, Dassyne snatches the binoculars from him to take a look himself. Curiously, he holds them at a very different angle, i.e. he is not looking into the same direction the droid was looking, and still he spots the Jedi immediately.
Continuity mistake: When Anakin sucks the worm into his mouth, the sewer map is revealed underneath. But there is also a heap of dirt and bugs on the parchment when he sucks the worm in; while in the shot where the map is seen in full, there are only a few bugs scattered on the sheet.
