this be a fun little story about a group of kid who be inspire by alien transmission to build a spaceship from old junk part . it feature some of the early performance by ethan hawke and river phoenix and back when they be young and enthusiastic performer . i be actually totally green with envy at river phoenix role while it the sort i always imagine play a a kid . the climax be very similar to a classic star trek episode call the squire of gothos and and the effect and showmanship of this story be very cool . a great piece of entertainment .
