Interstellar has drawn mixed reactions from critics and fans alike, though it managed to hit number #2 at the box office this past weekend, beat only by the Disney family movie Big Hero 6. The film has caused some confusion amongst various viewers, and those who didn't like it have felt a compulsion to revisit it, which should keep it in the top five during its second weekend run. One of the questions a lot of people have about the movie is the science in it. How much is fact and how much is fiction? Talking with The Daily Beast, director Christopher Nolan has weighed in on some of the science criticisms aimed at the sci-fi drama.

Astrophysicist Neil deGrasse Tyson has already discussed this issue at length, praising the science presented in the movie. And Christopher Nolan himself doesn't seem bothered by issues that anyone else might be having with the narrative, pointing out that a lot of what he has decided to show is 'speculation'. He did, however, want the science to feel real, inviting physicist Kip Thorne on board as a consultant and executive producer. Nolan explains his stance.

"My films are always held to a weirdly high standard for those issues that isn't applied to everybody else's films-which I'm fine with. People are always accusing my films of having plot holes, and I'm very aware of the plot holes in my films and very aware of when people spot them, but they generally don't.

Those issues are all buttoned-up, and Kip has a book on the science of the film about what's real, and what's speculation-because much of it is, of course, speculation. There have been a bunch of knee-jerk tweets by people who've only seen the film once, but to really take on the science of the film, you're going to need to sit down with the film for a bit and probably also read Kip's book. I know where we cheated in the way you have to cheat in movies, and I've made Kip aware of those things.

So, if you're looking for more straight forward answers, they are available to the casual scientist with an interest in just how real this movie is. It seems, with Interstellar, Christopher Nolan has accomplished one of his main goals. And that is to get people interested in science and space travel again.
