This impressive 11 part Planet Earth - The Complete BBC Series has the most astonishing sights and sounds you'll ever experience from the comforts of your home. Take your favorite drinks, food and begin the journey. All episodes are 50 minutes and you will want to finish all 10 hours without any break. This is undoubtedly one of the best documentary films about the nature and wildlife habitat (mountains, caves, deserts, shallow seas, seasonal forests, etc.). Entire planet has been magnificently represented for each region. It is one of my all time favorites.
