You’ve watched the various home video special features, but the upcoming doc Memory: The Origins Of Alien promises to tell you stories you’ve never heard and show you things you’ve never seen, Screen Daily reports. Paris-based Indie Sales just launched worldwide sales talks on the documentary out of TIFF, from director Alexandre O. Philippe (78/52).

“The filmmakers said Memory – The Origins Of Alien will reveal previously unseen materials from the archives of writer Dan O’Bannon and designer H.R. Giger, including story notes, drawings, designs, behind-the-scenes footage, and O’Bannon’s original 29-page Memory script from 1971. Philippe and Exhibit A Pictures have also conducted interviews of the film’s cast and crew, and relatives of O’Bannon and Giger.”

The doc was shot in 4K resolution, and is planned for early 2019 release to mark the 40th anniversary of the release of Ridley Scott’s horror/sci-fi masterpiece, Alien.
