There are various clips on Youtube as well. While I feel that in some instances "shock-footage" can inspire distortion of issues and acceptance of sound bites as fact (in place of data or at least comprehensive evaluation of credible information), I also feel that there are some things you just can't grasp without seeing. I don't know where the film makers get their numbers, so there's a risk of my having accepted less than credible sound bites so far, but the images of the fins are pretty compelling.
