The unveiling of the trailer for a new Cloverfield film caught everyone by surprise when it emerged in January; no one had known a sequel to the 2008 surprise hit was in the works and, what was more, the new film seemed to be completely different to the original, with the handheld camera and found footage style noticeably absent.
As if anticipation wasn't already high, the upcoming 10 Cloverfield Lane is JJ Abrams' first project, via his Bad Robot production house, since a certain sci-fi space opera smashed all box office records at the end of last year.
With the original trailer, the subsequent Super Bowl spot and the second trailer giving very little away, we were intrigued to visit New York and see a 25 minute exclusive preview of the film - although it was stressed that the footage was taken from different parts of the film, rather than necessarily being concurrent - followed by a chat with stars Mary Elizabeth Winstead and John Gallagher Jnr, and first-time feature film director Dan Trachenburg.
Despite the fact that the movie is clearly being designed to be as mysterious as possible, we managed to dig for some extra juicy titbits about the film: are any of those many fan theories correct? How does it connect to the original film? Is anyone else in it?
Read on for 10 key things to expect: beware of very mild spoilers but, excitingly, even we don't know for sure what's going to finally appear on that screen.
10 Cloverfield Lane is in Uk cinemas from March 18
