In 2008, J J Abrams and Matt Reeves' found footage horror Cloverfield was released in cinemas depicting a New York alien attack. Cinema goers were itching for more, even after spending the film length with their heads in their hands to prevent motion sickness.
Since then, Abrams has released two other movies within the Cloververse: 10 Cloverfield Lane in 2016 and Netflix's The Cloverfield Paradox in 2018, each with their own different style and genre but link in some way to the original.
Fans over the years have debated how much these movies really follow on from each other and what is in store of the future, with Abrams having confirmed a fourth instalment in the works since the last film's shocking reception upon release.
But which of these conspiracies are true? What hidden details are there after watching the trilogy? How do they fit together - or are they just three separate films with the same title?
Here is a list of just some things you probably didn't know about the franchise from the very beginning, and what may lie in the future for the next instalment.
