“Weren’t you lonely?” Elle Fanning asks “Game of Thrones'” Peter Dinklage in a NSFW teaser for “I Think We’re Alone Now.” The unlikely pair are living in a post-apocalyptic world, and Del (Dinklage) was convinced he was by all by himself before encountering Grace (Fanning). Rather than searching for other survivors, he was simply basking in the solitude that came with the end of the world. He wasn’t lonely. He was completely in control of his life, and happier for it. Until he met Grace.

“I’ll tell you when I felt lonely,” the misanthrope says. Check out the teaser to hear his answer.

“I Think We’re Alone Now” marks Emmy-winning “Handmaid’s Tale” director Reed Morano’s second feature. She made her directorial debut with 2015 Olivia Wilde-starrer “Meadowland.” Morano launched her career as a cinematographer with credits including “Frozen River” and “Kill Your Darlings.”

“I felt like it could be a very personal, subjective, psychological, and emotional examination of life in a post-apocalyptic world,” Morano said of “I Think We’re Alone Now.” “It’s not about why the human population has been wiped out: it’s a story about how you would feel if that were to happen.” She explained, “It’s about what human connection means to someone who never actually connected to people when they were around. At the end of the world, when there’s no one left anymore, the how and the why matter far less than basic emotional survival. It’s about how you live with it and how it changes you.”

The pic premiered at Sundance in January and took home a Jury Award for Excellence in Filmmaking.

Morano is currently filming “The Rhythm Section,” an assassin thriller starring Blake Lively. She’s also signed on to helm an untitled film about a narcissistic virtuoso violinist (Bridges) who is forced to move back in with his estranged wife (Lane) after he’s diagnosed with a life-threatening illness.

“I Think We’re Alone Now” opens in NY and LA September 14 and nationwide September 21.
