This Smithsonian Networks made for tv video has a lot of info, history and myth about these giant snakes. Taking you deep into the Amazon basin and Yanos of Guyana and filming on land and underwater hunt for the largest of these massive snakes, with the help of renouned experts in the field. The interviews with eye witness accounts of the indiginous natives, make this a compelling and riviting documentery. My only dissapointment was the unanswered question of weather the reward offered ( in the 1930s ) of $50,000 by New Yorks, Museum of Natural History, for anyone bringing back a snake of over 30 feet in length was ever collected. Many stories of snakes up to 100 feet in length, but no proof. Still many of these anacondas filmed in this documentary are massive and certainly reach over 20' in length with a couple approaching the legendary 30' mark. A very engaging DVD. Well worth the $5.23 including shipping, that I paid. Joe In San Francisco
