Star Wars Episode 5: The Empire Strikes Back - No Red (Rogue) Markings on Snowspeeders
When the rebel base on Hoth is attacked by Imperial AT-AT walkers, after about 20 minutes from the start of the movie, watch this blooper: The moment the snowspeeders are taking off to defend the base, you can see that there are no red markings on the snowspeeders. A few moments later, when they are approaching the Imperial walkers, the markings are there!
