Surprise! Found footage monster movie Cloverfield will get a sequel directed by Dan Trachtenberg, the amateur filmmaker behind excellent Portal fan tribute No Escape.
10 Cloverfield Lane will be a "blood relative" to the original Cloverfield, producer JJ Abrams told Collider last night after a trailer for the film unexpectedly appeared online. "We wanted to hold back the title for as long as possible."
Trachtenberg had been announced as shooting a low-budget post-apocalyptic thriller for Abrams' production company Bad Robot back in 2014. It's only now - with the movie shot and ready for release - we know it will be the long-rumoured Cloverfield follow-up.
US cinemagoers will get the film as early as 11th March, with the UK following close behind on 8th April.
The movie's post-apocalyptic storyline follows a family living in an underground bunker. Are they sheltering from the monster seen in the original Cloverfield, or has something else been awoken?
Trachtenberg was previously set to helm a movie version of graphic novel series Y: The Last Man, a job he got based on the quality of his Portal fan film.
However, Y ended up canned and the director took on 10 Cloverfield Lane instead.
And it's all thanks to Portal: No Escape, which notched up a million views in its first day on YouTube back in 2011. 16.8 million people have now watched the dark take on Valve's world.
