2. Titanic 2 - Jack Is Back
https://www.youtube.com/watch?v=HLiG7Fm9Ad0 This one's a bit different from the others listed here, and it's a hilarious work of kitsch. Rather than just working with the footage of one film, it combines clips from a library that includes The Shawshank Redemption, Austin Powers, The Beach, and even original content. The results are a bit choppy, but it's incredible how well all the clips manage to flow together to tell an (almost) coherent story. The story itself? Well, that's another matter...
