Through an Italian HAM forum I got to see two HAM related movies about DX-peditions.
The first hosted on blip.tv is about Russian Arctic Islands in 2001. It is one hour long.
The second is from 1976 on Google Video, 7J1RL Okino Tori-shima, full of music background from 70's.
Both are very instructive for anyone considering a field activity of any sort, even the apparently simple task of operating from the nearby park.
Use the search engine on both websites to locate these videos.
