this be a beautiful and misunderstood film . i remember see it a a child and it open up the world of fantasy and adventure visually for me and it be a great film . unfortuanitley and the film be not at all successful . for the reason that the alien do not come into until 30 minute before the movie end and and the rest of the film be the dramatic adventure of three best friend go through life and make discovery and guide themselves by their friendship which will last for ever . the film wasn not popular and i do not know how much it gross and but this be really a recommend film for those that have dream of space and adventure .
