I had this film on VHS as a child but can for the life of me not remember its name. I know it was a scifi/fantasy film.
There was a princess who had to be rescued frequently. In one scene she was wrapped up into a carpet by the bad guys.
There was some sort of fantasy castle and I think the whole movie played in space and there were spaceships. The hero had a sort of hero title, like "something-man" and I think the film was named after him, there might even be more than one film to this.
I'd guess it was produced in the 80s, but it could be older.
I'd wager the guess that it was animated in the US. It was very heroic and simple plot-wise. It had an anime-ish look to it, when it comes to character design, but I am pretty sure it wasn't an anime. I think it was rather crudely animated, with reused frames etc, which would make it something produced for TV/VHS. I was around 7 or 8 when I watched it, so my visual memory could be totally warped.
