The funny thing is -- this isn't a new film, but Kieth Merrill's 34-minute short from 1984. It's also a film that, according to the National Geographic website, has been screening in their Visitor Center every day for about 20 years. Talk about lasting power. The film covers "man's fragile kinship" with the canyon, and then goes into the history, from the Anasazi to Major John Wesley Powell.
Now, if this picks up, and other awe-inspiring geographical locations get short films, I'm hoping we get a 3D IMAX walk through El camino del Rey. Just watching the walk in a small frame is freaky enough. I can't begin to imagine what it would be like huge, and 3D.
