Here's a nicely done video of three guys' hiking the JMT:

John Muir Trail - A Journey Through The Range Of Light

It's long! 1 hour 25 minutes! Posted by John Amorosano.

Nice videography, and quality editing. I only watched parts of it, but it really captures the beauty of the hike. And I am really envioius of their fishing -- watch the section at 56-59 minutes!

Watch it full screen if you can.
