Star Tours: Although this ride is still active, it has undergone some changes. One such change happened long before the 2011 update to a new 3D version of the ride. Originally, the outside of the attraction featured a Snow Speeder from the Empire Strikes Back. This was later removed and can be seen in the Backlot Tour.

The original pilot “Rex” has since been replaced by C3PO. However, he can still be seen in the second queue room for the attraction. Rex is now marked “defective” and is on the way out for repair.
Also, the two robot birds that once sat over the entryway near the G2 droid in the original queue are now caged near Rex, and are no longer animated.
Look for the G2-9T droid in the queue as well. This was the droid that originally sang “I’ve been working on the same droid, all my livelong day.” He now says “this job is a lot better than, say, fixing broken droids all day.”

Lastly, the lady in the original safety video for Star Tours reappears in the new safety video, but is merely a passenger in the second row of the speeder (wearing purple).
