Interstellar is Nolan's first film since wrapping up The Dark Knight trilogy and stars Matthew McConaughey and Anne Hathaway as astronauts who must find a new planet to replace a dying Earth. In addition to the high-stakes premise, the emotional aspect of the tale focuses on Matthew's character -- a father grappling with the conflict of having to leave his children behind for a larger cause: survival of the species.

Matthew told ET last month that his real-life children played a part in his decision to do the movie.

"The main impetus in my gut was I want to do this for my son, Levi," said Matthew. "He came to set and he saw all of our shuttles and the Endurance and everything, and he got to take some practical rides, and it was real for him. It was better than Disneyland."

Anne admitted to ET last night that she didn't actually understand the end of the movie throughout the entire filming process.

"The second time watching the film -- after having read the script probably upwards of 70 times -- I ran up to Chris [Nolan] at the end of the screening and said, 'Oh my god! I understand the ending!'" Anne shared, laughing. "He said, 'Wait a minute, like, just now?' and I'm like, 'Yeah, just now!'"

"I think he was a little disappointed in me," Hathaway added, "But I didn't care because the movie is awesome!"

Before the wide release on Nov. 7, Interstellar will have a special opening at the Smithsonian's National Air and Space Museum IMAX theaters today. The event will include the world premiere exhibition of the Ranger spacecraft from Interstellar, giving visitors a look at the spacecraft built for the film.

Interstellar also stars Jessica Chastain, John Lithgow and Michael Caine.
