Do you like sci-fi?
Are you fascinated by the Soviet Union?
What about non-annoying smart teenagers?
Watch Moscow-Cassiopeia and Teens In The Universe, Soviet comic science fiction movies that have a nearly all-teen cast. (They need to be young, so that they'll survive a 52-year mission to alien life orbiting Alpha Cassiopeiae.)
