Question by Gunner 11: What’s the name of the movie where these kids make their own spaceship and go to space?
It looks like its made in the 80s; there is one really dorky kid with glasses and another guy and girl. They go to space and make alien friends and at the end of the movie the aliens parents come and ground them.
