Originally presented in IMAX theaters, LOST WORLDS looks at untouched aspects

of nature in parts of the world where humans rarely tread.

From plants, to animals, to geology,

this artfully photographed documentary presents facets of the biological world that you are not likely to see anywhere else.

What happened here? What keeps all civilizations alive? To find out, join narrator Harrison Ford on a scientific adventure from the arctic to the equator. Tunnel into a metropolis of micro-organisms beneath New York, swim through the underwater forests of the Pacific, and climb to the top of the mysterious mountains in Venezuela that inspired Arthur Conan Doyle's novel The Lost World. Discover the wonders of biological diversity—and its importance to all of us.

This starts with the Mayans and their lost civilization. Narrator Harrison Ford examines the resources connected to New York City and follows the water up the pipe back to the nature reserves which filters and protects the city's water. Nature's bio-diversity cleans and preserves the water. A team of biologists head off to the mountains of Venezuela which is the inspiration for Sir Arthur Conan Doyle's The Lost World. The central theme of this documentary is the connection between the city and nature.

This is a 40 minute documentary probably meant for the IMAX theaters in museums. It has the sweeping vistas and fly-bys that those movies really love. It's connecting the artificial city world with the natural world. It suggests that the city needs nature to survive and wonders about the lost ancient civilizations. It's great to connect the two worlds which often feels disconnected. It's a worthwhile premise which this short does very well.

"Lost Worlds: Life in the Balance" is another 40-minute IMAX presentation and this one is about the nature as a wonder of the world we have to preserve at all costs. It also centers on many beautiful and fascinating species we know and how these are only a low percentage of all these that exist. We need to keep them from going extinct. All in all, this is very much by the books. Some solid nature photography, breathtaking cinematography and some concrete example that keep the film from becoming too distant and too general. The only thing I did not like is that they included 2 narrators. Obviously they wanted to list Harrison associated with this project as he was still a much bigger star back 15 years ago than he is today, but why include another narrator, that one is female, too? Yes we do see her, but still.. A 40-minute film does not need 2 narrators. If I look beyond that, however, it was a pretty solid watch and I recommend checking it out to everybody who loves nature documentaries. Thumbs up. It was very much obvious that the people who made this have a lot of experience in the genre.
