For my Literary Genres: Short Story class. I made a presentation on the short story The Sentinel by Arthur C. Clarke and its movie adaptation, 2001: A Space Odyssey. Even though 2001: A Space Odyssey isn’t an exact adaptation for The Sentinel, they both have the same concepts and themes that run through the short story and the movie. The other reason why The Sentinel is referenced as the story that inspired the movie is because Stanley Kubrick and Arthur C. Clarke(who co-written the movie with Kubrick) used The Sentinel as the basis for the movie.
So here is the PowerPoint I used for the presentation. Fake Internet points for anyone who gets the references.
