For those who like intense movie action and lots of special effects, then this has to be one of the best nature documentaries there is.

The creator of this video combined high tech special effects like those used in video games and movies with real documentary footage of bats and crocodiles, to create the ultimate battle between the two.

There are some brief moments where the original footage appears intact, but for the most part, this is a scene comparable to 'Halo' or 'Star Wars' depending on whether this looks like a video game or movie to you.

While this documentary is probably exciting without all the extras, they add an element that makes this the most epic battle of all time. Who knows what could be next? Maybe a destructive battle between field mice and owls.
