In the interview, Abrams explains how the new movie is connected to the original, and how it will be different.
In particular, he reveals that the LSA (Large Scale Aggressor) monster from Cloverfield will not be in the new movie, but there will other monsters:
There is a monster in this movie. It’s not the monster you expect, but there is a monster. The thing that I will say about anyone who is going to it expecting to see literally Cloverfield 2, those characters and that monster are not in this movie, but there are other characters and other monsters.He also explains that the scenes for the trailer were shot first, just like the first movie, so the movie could be released in a short time frame:
We thought, “When was the last time a movie drops a trailer for a title that no one had heard of two months before the movie is to be release?” Not often. We thought that was fun ... Literally, my pitch to Brad Grey on that was to start by shooting the trailer first, which we did.Abrams hints that if things go well, a third movie could eventually be made (hopefully not in another 8 years...)
This movie felt like we had an opportunity to do something that was similar, surprise the hell out of people.
I would be lying if I didn’t say there was something else that, if we’re lucky enough to do it, could be really cool that connects some stories... This is just this movie, and it’s only two films that we’re talking about right now. There is something else that we’d like to do, and hopefully we’ll get a shot.Check out the entire interview at EW.com
