Rent World's Most Dangerous Animals: Anacondas (2003)

This all-action adventure takes intrepid zoologist Nigel Marven on a whistle-stop tour of South America as he hunts for an Anaconda measuring more than 30 feet. First stop is Venezuela, Green Anaconda heaven. Nigel finds the low lying serpents with his feet, but has to use all his strength to wrestle them into a position where they can be measured. There are no giants on this visit so he makes a little detour to find snappy Yellow Anacondas in Brazil. Nigel watches these 10-foot serpents feed with one even attempting to engulf a huge stork. Nigel then heads off to the heart of the Amazon where in a spooky, moonlit creek, he finally meets up with his quarry. Will it be the giant he craves?
