2001: A Space Odyssey is considered a masterpiece, and a game changer for sci-fi on film. But the movie had a tumultuous origin story, and it was initially scorned by critics. Barbara Miller of The Museum of The Moving Image walks me through their new exhibit on the making of 2001. And I talk with author Michael Benson, actor Keir Dullea and Stanley Kubrick’s daughter Katharina about how Kubrick and his collaborator Arthur C. Clarke reached for the stars -- but felt lost in space as they struggled to finish this incredibly ambitious project.
