I'm not going to hide my bias, I am a Christopher Nolan fan. The only film of his I actively dislike is Following, his very first film. I think Interstellar is the best sci-fi film of this decade. He's one of the few directors of this generation that people can safely call a "visionary" because he's allowed to make the films he wants with very few restrictions. And he's earned that right because he really is a damned good director. I won't suck his dick like IMDb does (I mean, come on, this movie had an average of over 9.0 a week before it even came out), but he still is one of my favorites working today.
Naturally, I had to catch his take on World War II, because it seems like every notable director has to do at least one war film in their lifetime just to see if they can. Nolan's film specifically focuses on an event that surprisingly hasn't had more movies made about it: the daring rescue attempt of over 400,000 troops from Dunkirk, France. Considering we have 13 billion movies about Normandy or Iwo Jima, it seems odd that a major turning point in the war, from a moralistic standpoint, has been largely ignored in the media (Spoiler: It's because America wasn't involved). So it seems appropriate that Nolan, a British man, decided to use his seemingly infinite clout in Hollywood to get this film made. In IMAX, of course.
