This special features some of the original plans for the prequel trilogy, as well as some 1970s television silliness.
Michel Parbot filmed a lot of behind-the-scenes footage and interviews during the filming of The Empire Strikes Back. Some of it was used in a French documentary, while the rest ended up on Dutch TV. The French documentary was included in the Star Wars blu-ray release, while the Dutch footage has only been seen in a few very short low quality clips on the internet.
Now Star Wars Archives has uploaded an almost complete version of the Dutch TV special in a much more watchable quality.
