Game of Thrones star Peter Dinklage’s new movie, I Think We’re Alone Now, and the first released trailer is wonderfully creepy.

Peter Dinklage is currently rocking the Seven Kingdoms in Game of Thrones, and while we love him as Tyrion Lannister, it’s exciting to see him stretch his acting range now that Game of Thrones is ending and he’s beginning his post-Thrones life. One such endeavor is his new film, I Think We’re Alone Now.

A teaser was released for the movie, and while the details of the film are sparse in the trailer, it’ll definitely pique your interest. The movie focuses on life after most of humanity is wiped out, but the teaser hints at the idea that Dinklage’s character isn’t as alone as he thinks. And the trailer definitely gives you some major creeps as you wait to see what lies ahead.

I Think We’re Alone Now stars Elle Fanning alongside of Dinklage, and the film’s basic synopsis explains that Del (Dinklage) manages to create a sort of utopia for himself after all of humanity is wiped out. Del lives a happy life of solitude in his small town until Grace (Fanning) shows up, wanting to stay. Her past and her motives are unclear, and Del must decide how he wants to respond to this new interloper.

The movie sounds like it’s one you can’t miss, and a bit of a twist on the “last man on earth” vibe where we often see the planet’s sole survivor trying desperately to find any other sort of human connection out there. This film turns that on its head by following a guy who relishes (or at least doesn’t totally hate) the solitude and must decide what to do when that peace is interrupted.

We’ll be keeping our eyes out for a longer trailer, but with two talented actors in Dinklage and Fanning, this movie is bound to be amazing. You can catch it when it releases on September 21, 2018.
