The tagline for Christopher Nolan‘s Interstellar is “Mankind was born on Earth. It was never meant to die here.” In all the discussions about the film post release, that idea has kind of been left in the dust (pun intended). The environmental issues in the film have been overshadowed by the science of the space sequences, and the sound in the theater. Hoping to focus attention back on that aspect of the film, Nolan and his team are doing a project to celebrate the planet we live on.

Nolan and his actors are asking fans, filmmakers and everyone in between to participate in a time capsule project. An Interstellar documentary, if you will, that will result in a film that showcases “memorable and inspiring moments of today to give future generations a way to remember where they came from.” David Brodie and Angus Wall are producing the film with Nolan curating the entries.

Below, watch a video pitch from the cast of Interstellar and read more information about the project.
