It has achieved what most movies in this technologically advanced, social-media using age has failed to do so -- to keep its secrets, and prevent leaks from spilling over into the Internet. Which makes the Interstellar movie plot all the more intriguing for fans. Ahead of the Interstellar movie's release date, The Hollywood Reporter did an in-depth interview with director Christopher Nolan (Dark Knight, Inception), and his three main stars to find out more of what they can about this new movie that is sure to be a sci-fi epic.

Among those that participated in the discussion -- lead star Matthew McConaughey, Jessica Chastain, and Anne Hathaway. Several interesting thing came up during the discussion, giving fans more insights into the Interstellar movie plot. Among those discussed was whether space travel between galaxies was in theory, a possibility. The movie had as its consultant, theoretical physicist Kip Thorne, and what can be seen in the movie is within the realm of actual possibility. Says Nolan, "If a wormhole could be brought into existence, it would be possible. It's really one of the only ways it would be possible because the distances involved are so vast."

There is also a reason that Christopher Nolan's films looks so real and so raw. The director always tries to avoid computer generated images in his movies. In fact, the director has spoken of the Interstellar movie plot as "immersive" not just in terms of the storyline and the way that audiences view the movie, but also in its use of very realistic imagery. In Interstellar, the Dark Knight director looked to "what older films were able to do." He added, "One of the things we did was, we screened a print of The Right Stuff, an amazing film. And we looked at what they had done technically in 1983 with reflections of visors and things like that."

And as in many of his films, the director's foray into the sci-fi world is not one that he wants audiences to completely understand. He was asked in the interview if he intended for the Interstellar movie plot to be fully understood. "I don't think it does. And I think that 2001 is one of those rare instances where it's a purely cinematic narrative and it really tells you that it doesn't need to be understood - it needs to be felt. "
