Orson Welles — with contributions from scientists George Wald, Carl Sagan, and others — examines the possibility and implications of extraterrestrial life. In examining our perceptions of alien 'martians' from his "War of the Worlds" broadcast, to then-modern explorations of Mars, this film from NASA provides a unique glimpse at life on earth, and elsewhere in the universe.

An edited version of the 1970 German documentary "Erinnerungen an die Zukunft" (Chariots of the Gods), this examines the theory that aliens have landed on Earth in ancient times and were responsible for many of mankind's oldest mysteries.

Wanderers is a vision of humanity's expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available. Without any apparent story, other than what you may fill in by yourself, the idea with the film is primarily to show a glimpse of the fantastic and beautiful nature that surrounds us on our neighboring worlds - and above all, how it might appear to us if we were there.

Carl Sagan covers a wide range of scientific subjects, including the origin of life and a perspective of our place in the universe.
