The First Hollywood movie to have its premiere in Fiji.
Within the movie it is explained that the bloody orchid blooms every 7 years and the movie passes in 2004, therefore the orchid bloomed in 1997, the year in which the events of the first anaconda occur.
The film shows Green Anacondas in Borneo. In real life, green anacondas are not bornean species, they are actually endemic to Venezuela, Brazil, Colombia and Peru. In Borneo the closest thing to a green anaconda would be a python.
This sequel tries to give an explanation to the previous movie, showing why green anacondas are so gigantic. In the story the blood orchid is present in the food chain allowing them to live longer and therefore grow more.
The titular flower, the blood orchid, is actually real, but they don't have the immortality effects that the film says they have. They are a type of Orchid that's part of the Orchidaceae family. Orchid flowers come in various shades, including deep pink, blood-red, and brownish-red.
