I'm a big fan of Christopher Nolan's work and have been looking forward to Interstellar since it was announced following The Dark Knight Rises. One of the things I most appreciate about his films is his desire to keep it real, and to keep the "science" in science-fiction. Equally cool is how his determination to capture the authenticity of black holes for his new film helped researchers learn new things about black holes. Check out the story at Wired for the full scoop!
Also worth a look is this much briefer piece about living on Mars. Cool stuff!
