The actors are all grown up, some gone, others will be with us hopefully for a long time yet. As you may have guessed I liked this film. It teased with the thought that this could have happened. The whole bit was possible, not probable I'll concede, but every space struck youngster must have laid in bed and dreamed of this happening to him or her.The stars were healthy looking, pretty outgoing teenagers, not I'm happy to say, the overstuffed Barbie's of so many movies. They got across the acting bit in a natural way which struck true.That alone was remarkable. The grown up's had the easy natural feel about them that good character actors always seem to have.They become the character they play. I have seen the movie several times when I am relaxing, when children and grandchildren visit. I still watch with a smile on my face.
