I was up late last night as news broke of a teaser trailer playing in front of Michael Bay’s 13 Hours that may or may not be a sequel to Cloverfield.

It was eventually confirmed that J.J. Abrams had in fact produced a film in secret, now titled 10 Cloverfield Lane, and had it slated for release through Paramount Pictures on March 11, 2016.

Dan Trachtenberg directs this mystery film with Red State‘s John Goodman, The Thing‘s Mary Elizabeth Winstead, and John Gallagher Jr. starring.

The trailer leaked, now presented in HD below, and revealed a plot very different from Cloverfield. In it, the trio mentioned above are trapped in a bomb shelter. As the trailer darkens, the audience is led to believe that Goodman’s character may be bad, especially when Winstead’s character escapes. The button, though, sets up the mystery. What does she and what is Goodman referring to?

So, here we are with cool content but more questions than answers. Is this a sequel to Cloverfield? Probably not. Is it a spinoff? More likely, especially since Abrams called it a “blood relative” to the 2008 film.

Is there a monster? Are there monsters? What the hell movie is this? Paramount sent us the official teaser one-sheet that really pushes on the bomb shelter plot, but also gives a huge nod to the Godzilla-sized creature from the first film: “Monsters come in many forms.”

Now, is Goodman this film’s “monster,” or is this eluding to something else? Something I did notice in the below teaser is that Goodman’s character has a bandage on his head while they were all acting normal – and at the end we see why he has it. So, maybe Goodman isn’t the movie’s antagonist and he’s just a red herring?

Nobody knows right now except for a select few. But the mystery and anticipation is already making this more fun than anything else in recent memory.
