Hello there,
I'm looking for the name of an anime film which is quite old ('80 I think).
Its about 3 guys (a fat one with short t-shirt and his bellys out, a tall thin guy with glasses holding an umbrella and a short guy which think he is a karate guru). They find a spaceship with a blonde long hair princess with her crew and tshe take them to her planet).

Im looking for the name of this anime many years now.
If someone can help Ill be really thankful!

Yours trully,
