4. Cloverfield 2
Cloverfield was a sleeper hit in 2008, making $170 million worldwide after being made for merely $25 million, and gave new lift to the "found footage" filming technique that has been heavily mimicked in the 5 years since its release. It featured six friends attending a going-away party the night a monster attacks New York City, and their journey across the city during the attack as it's captured on a friend's camera. The film was directed by Matt Reeves, produced by J.J. Abrams and Bryan Burk, and was written by Drew Goddard (who made his directorial debut with last year's big hit, Cabin in the Woods). All four of them have expressed their excitement and desire for a sequel, though little has been done to make it happen: they're all extremely busy working on other projects, which makes it difficult to get everybody together for a project of this kind. They have, however, released various statements about their ideas for a follow up. They've expressed a desire to only do it if they felt excited about it, rather than a way to simply piggyback on the success of the first one. Reeves had this to say at the film's premiere about a sequel:
"While we were on set making the film we talked about the possibilities and directions of how a sequel can go. The fun of this movie was that it might not have been the only movie being made that night, there might be another movie! In today's day and age of people filming their lives on their camera phones and Handycams, uploading it to YouTube... That was kind of exciting thinking about that. There's a moment on the Brooklyn Bridge, and there was a guy filming something on the side of the bridge, and Hud sees him filming and he turns over and he sees the ship that's been capsized and sees the headless Statue of Liberty, and then he turns back and this guy's briefly filming him. In my mind that was two movies intersecting for a brief moment, and I thought there was something interesting in the idea that this incident happened and there are so many different points of view, and there are several different movies at least happening that evening and we just saw one piece of another."
It's certainly an interesting idea and would make sense with regards to the first movie. Let's hope we get to see this happen someday.
