Pardon me if this has been discussed before, I looked but did not find.
In Ep 2, after Zam shoots her assassin droid out of the skies, Anakin catches Obi-Wan on the back of the speeder he "borrowed". When Obi-Wan slides into the passenger seat of the speeder, he slides between the 2 headrests and when he does so, that area is completely smooth. However, before and after that scene, there are 2 rather large antennae sticking out right there. The strangest part is they seemed to be physical changes to the prop from what I saw on the Ep 2 DVD documentaries, so they had to actually build 2 different sections of the speeder (or worse, 2 different speeders) for the shot - did they know about this change before they started or did it come up on the spot? Did they simply want to gloss over the change or did they try to think a way around this slight continuity problem?
