This film based on Ojibwa (chippewa) and Algonquin Native American Legends.
I had expected this film to center mostly around this but it was only a small part of the plot.
The Wendigo, Windigo, or Windago is a spirit that comes with the wind. It would entice persons by calling to them in an irresistable way. It then would drag its victims along at great speeds until they burn up.
This film mostly centers around a family that vacations un upstate New York during winter and have an unpleasant run in with some local hunters. This film has some excellent cinematography and special camera angles. There is much time-lapse photography and one part with the now-famous "time slice" photography better known as "bullet time" which was made famous in "The Matrix (1999)"
It is an unusual film and I could describe it as a combination of Blair Witch, Sixth Sense, Abominable Snowman.
