One of the big movie surprises of the year so far was the announcement of the JJ Abrams-produced 10 Cloverfield Lane. The mysterious new thriller is released next month, and is seemingly connected to Abrams’ 2008 monster movie hit Cloverfield. A new trailer has been released–check it out below:

Abrams has described the new film as “blood relative” to Cloverfield. It is directed by Dan Trachtenberg, and stars Mary Elizabeth Winstead, John Goodman, and John Gallagher Jr.

Last month, Winstead discussed the secretive nature of the project. “We were making this movie in this little bubble,” she told EW. “Nobody else knew what we were doing and there’s really only three actors in the whole thing, so it kind of felt like this really intimate experience.

“Now that it’s about to come out, it’s sort of crazy–like, ‘Oh yeah, people are excited to see this movie.’ I forgot that that was going to happen.”

It has been rumoured that the film was originally shot as a standalone movie called Valencia, which was rewritten and retitled in 2015 to tie it into Cloverfield. In 2014, Winstead referred to the production as Valencia, as did Variety when Goodman’s casting was announced. In the interview with EW, Winstead commented: “As production went on there were rewrites, as there usually are, but nothing that was major.”

10 Cloverfield Lane is due to be released on March 11, 2016.
