Are we alone in the universe? It is one of humanity’s oldest and most enduring questions — one that has inspired science, philosophy, and popular imagination for generations.
In the remarkable 1975 film *Who’s Out There*, legendary filmmaker and actor Orson Welles joins leading scientific minds, including Carl Sagan and Nobel Prize winner George Wald, to explore the possibility of extraterrestrial life and what its existence could mean for humanity. From perceptions shaped by *War of the Worlds* to scientific investigations of Mars and distant worlds, the documentary offers a fascinating look at how humans imagine life beyond Earth.
