This is from the new series, "Planet Earth" on Discovery in the US. It was filmed over 5 years and has some of the coolest video I have ever seen.
Well, this weeks episode of "shallow waters" topped everything. The following link is THE coolest footage I have ever seen of shark hunting. It's about 3 minutes long, but worth it especially the very last attack and how much air this 1 ton shark gets off the water...
and the above video really doesnt do justice as the filming was done with HDtv in mind, so the quality is amazing even on a regular tv.
