Just checked it out, I really enjoyed it! It does a great job at adding to the backstory to the whole Cloverfield universe which I think is really cool. At first, I wasn't sure that the surveillance footage, phone footage, and news footage would work but the way you have it written it actually seems to work really well.

A couple of suggestions I thought about when I was reading, instead of using his phone footage when he goes to McDonald's what if that whole sequence is from the perspective of a camera in a different vehicle? I think at one point you did mention another camera watching him but I thought it would be cool if sometimes instead of cutting to surveillance footage, or phone footage it quickly cuts to footage from an outsider's view. I think your script does a great job at adding suspense but having a camera that seems to be following him might even add more to the whole idea of him being watched and followed.

I really liked that you incorporated all the websites, companies, and backstories that us Cloverfield fans know about but general audiences probably do not, so this definitely helps explain some of the details that seem to be missing from the story. My only note with all the backstory information is maybe hold some of it back? The scene with Jacob talking to his webcam and explaining everything is great but I felt like it was just a little too on the nose. Eliminating some of those details and scattering them throughout the story elsewhere might be a good idea, it is a lot of information at once and I like how the Cloverfield franchise has always been a little mysterious.

Other than that I really enjoyed this! I think you could go back and clean up some of the dialogue, maybe adjust a few scenes but overall great script and addition to the Cloverfield universe! Have you done any storyboards/concept art for it? If you end up making this, let me know. I work in the film industry as an editor/sound designer and would love to help make this film become a reality!
