While the chestburster scene in director Ridley Scott’s 1979 sci-fi horror classic Alien still haunts me, it’s because of Alien’s originality and complex creatures that I grew up loving horror films. Now fans like me can continue to celebrate the movie’s 40th anniversary with a new documentary called Memory: The Origins of Alien.

The first trailer for the documentary shows exclusive behind-the-scenes footage that gives fans the untold origin story behind the movie.

My wife didn’t believe me that Alien was “just” a “there’s a monster in the house!” horror movie until we watched it again. But it’s a great horror movie.
