From the acclaimed filmmaker behind legendary sci-fi films The Terminator, Aliens, The Abyss, Terminator 2: Judgment Day and Avatar, this documentary series explores the evolution of sci-fi from its origins as a small genre with a cult following to the blockbuster pop-cultural phenomenon we know today. In each episode, James Cameron introduces one of the “Big Questions” that humankind has contemplated throughout the ages and reaches back into sci-fi’s past to better understand how our favorite films, TV shows, books, and video games were born, Cameron and his contemporaries – Steven Spielberg, George Lucas, Ridley Scott and many more who have helped fuel sci-fi’s spectacular growth over the last several decades – debate the merits, meanings, and impacts of the films and novels that influenced them and discuss where the genre — and our species — might be going in the future.
