In 1979, the French journalist and director Michel Parbot filmed behind the scenes of The Empire Strikes Back. His footage appeared the following year in two TV documentaries (one American, the other Dutch), but while the American documentary ended up on the Star Wars Blu-rays, the Dutch one reportedly remained holed up in the archives of LucasFilm and of two French TV broadcasters, leaking out only in low-quality snippets.
The documentary provides a (sometimes funny) view of Star Wars behind the curtain. During the filming of the Hoth battle scene, a snowstorm comes up; the crew rushes to protect the cameras and props, pulling a full-sized Tauntaun across the tundra with a snowmobile. Later, a headless Wampa takes his first wobbly steps—and face-plants. There’s also the uncomfortable fact that Hamill keeps saying that Luke would like to put the moves on Leia himself; as Return of the Jedi fans know, the two characters turned out to be siblings.
