The "Interstellar" movie trailer is out, the film made more audience-friendly by "Inception" director Christopher Nolan.

Director Christopher Nolan admitted he struggled with the screenplay for the new film, with the "Interstellar" movie trailer released. Nolan plans to unravel the plot in a way the audience can directly relate to, and calls the shots on which concepts to include in the production.

Nolan is known for the box-office hits and critically-acclaimed films "Inception" and the recent Batman film trilogy.

A prep interview for the film, which now screens to a test audience, has Nolan grappling with the science of the film and the amount to include in the output.

"Kip [Thorne]'s research into the mathematical possibility of wormholes, the fact they can exist, gives you a way that this could happen and was essential to the jumping-off point in the story. When I came to the project, [Kip] and Jonah had worked on a vast array of ideas involving a lot of the different things you're talking about. And one of the most important parts of my job was to say: 'OK, we can't use all of this. I'm going to have to choose.'"

Nolan filtered much of the science of wormholes and light-speed travel to make it more accessible to the audience.

"We would get into long debates about, [can] you go faster than the speed of light, and those kind of questions are a little frustrating to a physicist. We'd meet pretty regularly while I was writing. [But] certainly when Matthew came on board, the more focus it seemed to give on who these people are as human beings."

With the "Interstellar" movie trailer out and advance screenings for the film is earning rave reviews, the new Nolan flick is expected to be another hit at the box office.

The "Interstellar" movie release date is pegged November 4 (cinemablend.com).
