DO NOT watch this movie only because you heard that it inspired Star Wars. Here are the things from this movie that appear in Star Wars:
1. The thread of the story follows two bumbling, low-class characters that stumble into a much larger story.
2. Wipe transitions.
3. A strong female protagonist.
Now that we have that out of the way, you should watch this movie on its own merits. It's arguably too long, but still well made and well done.
