Darren Aronofsky’s new 18K picture Postcard From Earth had its world premiere at The Sphere in Las Vegas, a love letter to a planet that aims to encourage audiences to feel a little more protective of it.

The 50-minute film begins with a sci-fi feel, as two characters land on a new planet via spaceship. While in their spaceship, a voice begins to remind them of the Earth they left behind.

Suddenly, pristine footage of the planet fills the 16K x 16K screen. The voiceover, which is used somewhat sporadically to allow the images to shine, describes Earth as a “wonderful symphony frozen in time.” Canyons, grasslands, mountain ranges are featured, according to Rolling Stone.

While some elements were new to Aronofsky in the making of the film, the content was not, as he had extensive experience shooting natural history documentaries for National Geographic. “Postcard From Earth” is like a National Geographic film on the screen of The Sphere global arena for music and entertainment, which is the size of four football fields, the publication notes.

The Sphere at the Venetian Resort in Las Vegas, has a capacity of 18,600 people and opened its doors with the concerts of U2 and the specially designed project of Darren Aronofsky.

“I had no idea what an 18K image would look like on a screen the size of four football fields. I really couldn’t imagine the resolution or what it would be like,” the American director emphasized in an interview with Variety.

“I didn’t want to just have the most beautiful images we could create, with voice. I wanted to try and see if I could add an emotional narrative to it as well. And that was the challenge we faced. How can we combine fiction and documentary and make something new?” he reported.

Darren Aronofsky explained that he worked with producer Ari Handel for several months and emphasized that he would not call the film dystopian.

“It’s undeniable what’s happening on the planet right now and it’s a terrible situation. But I think we need stories that envision a future where humanity has found a balance to live with Mother Earth. And I think that’s now the job of storytellers, to start figuring out how to tell stories that inspire people to connect with the planet and find a better outcome for where we seem to be headed,” he noted.
