"Groups seven and ten will stay behind to fly the speeders." - Rebel Captain
During production of Episode V, filming the Rebel Alliance's snowspeeders was a time-consuming task. Many of the scenes involving the speeders zooming through and around the screen were actually shot with a motion control camera moving very, very slowly past the models. The crew at Industrial Light & Magic would spend 3 to 4 hours programming the motions of one speeder and about 5 minutes filming it at a slow speed against a bluescreen. It would then take days or weeks to get all the mattes combined with the snow covered backgrounds they shot in Norway. Sometimes the shadows of the speeders were animated, while other times a separate exposure of the real model on a white card was taken, then placed optically underneath the previously shot footage.
