Go to www.interstellarmovie.com and enter the "access code" 7201969 (yes, a little silly) to see the third trailer in high definition.

The final shot of this trailer, by the way, is of the spaceship in front of a black hole with a thin accretion disk. The image is, as far as I know, the first visually accurate image of a black hole ever used in a Hollywood movie. One particular point to note: the disk only appears to bend upward on the back because the photons of light that carry the image are bent downward by the black hole. Writing a code to produce this image (without the Hollywood flair, of course) was a homework problem in Caltech's GR class when I took it.

Also, the "inner ring," just barely appearing to surround the hole in the image, is *not* a second accretion disk, or even a wispy offshoot of the bigger one. It is a secondary image of the *same* accretion disk, caused by the fact that photons get dragged around the hole multiple times before they can reach the eye, producing multiple images.
