The idea is that a sultan prince has been turned into a baboon on his coronation day and Sinbad, his crew, a wise man and a princess need to travel to the North Pole to find the means to transform him back.
On the understanding that there is no oportunity to rate it 0 stars. . . .
Why was it so rubbish? Here are a few, a few mind, examples.
1 - The evil sorceress creates a mythical and magical monster. They then use it to row across the world to get killed opening a door. . . .
2 - The sultan and all his companions save one are aparently British. . . . .
3 - When they can not find an entrance to the final tomb, they pull it appart at exactly the right place for the entrance! Lucky or what?
4 - They have seven moons to get the prince crowned. So obviously it takes 4 moons to get to their destination. . . not sure how they were going to get back in three. . . .
5 - Time is of the essense. Therefore the gals should frolic naked in a warm pool before they reach their destination. Obviously the big monster takes this opportunity to attack them and they have to run naked for help! Okay this was was partly
and partly 
6 - The lead actress obviously got paranoid about her sidekick. Princess = no clothes. Side kick = brown lumpy, shapeless smock.
All in all very stupid film. I had better stop now before I get the feeling I wasted 2 hours of my life. :D
