Star Wars Episode 2: Attack of the Clones - The Disappearing/Reappearing Antennas
This is pretty close to the beginning of the movie, probably barely 20 minutes in.
During the scene after the bounty hunter Zem has tried to assassinate Padme, Obi-wan is hanging on to her/it's little assassination worm carrier which Zem shoots causing Obi-wan to fall. At this time, Anakin has hopped into a flying convertible yellow car type ship and is following close. If you look behind him on the back of the car between the driver and passenger side, you can see two big antennas stick up on the vehicle.
However, when he zooms low to catch Obi-wan, the top view shows the antennas have "magically" disappeared. Obi-wan latches onto the back, and then kicks his feet around and over into the passenger side, right where the phantom antennas would be. After he drops in and the camera has switched back to a font view of the two actors, we see the two antennas have regenerated back to their positions. Who knew Star Wars ships could do that?!
