Who's Out There?

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.
