Explorers. 1985.
A young boy obsessed with science-fiction movies has a recurring dream and is able to describe a blue print of his dreams. Along with his science geek friend and his computer and a third boy, they build a spaceship and they begin to get signal and try to follow it.
Ethan Hawke, River Phoenix and Jason Presson play the three friends who use a old Waltzer and other stuff from a junk yard to create a home made space ship and introduced to a alien race voiced by Robert Picardo and the aliens can be a laugh. Joe Dante done a decent job with this family friendly movie that can have it's laughs and a small appearance from Dick Miller who goes on the trail of the home made ship.
