Apparently the movie is bad, as in really bad, but you can't argue with awesomeness and greatness of this poster, done in a time before Photoshop when movie art was an actual thing. I tried to find out who the artist is online, but couldn't. It's not Boris Vallejo, but it's a contemporary of him. I'm sure I saw this in a Fantasy Art book from my youth, so I have to try remember what other names were out there with a similar style. Until then, we'll just have to bask in it's anonymous glory.
