About 30 years or so ago, I remember watching a Japanese cartoon on tv....I can't remember what it was called...but I remember it used scenes directly taken from the first "Star Wars" movie...I remember being amazed that they were able to get away with that, but it was very well put together. I've been looking for it for years...even contacted my friend who had it on VHS back then, but he couldn't remember what it was called either. Can ANYONE out there help me figure out what this movie was called? I'd really like to find it again.
Perhaps you mean Droids, the Star Wars cartoon? It was around in 1985-86, and featured Star Wars cuts -- because it was a Star Wars product.
Additionally, there was the loathed Ewoks series the next year.
If it was a music video, you're probably remembering the Daicon IV animation, which was a fan parody (details here). It does indeed have scenes that include Darth Vader, stormtroopers, TIE fighters, and such. They "got away with it" because it was made to be shown privately at a fan convention; not distributed internationally.
It's relatively short, though, at 6 minutes long; not a full movie.
