In 2001, a documentary called The Great North was released, it was filmed at Hudson Bay, Canada. The documentary was made in IMAX format. In one of the scenes, a Bigfoot can be seen. The scene in question is the great caribou migration, in that scene you can see a Bigfoot pop out looking at them. For a few seconds the Bigfoot is seen following the caribou, then it hides and never appears for the rest of the entire documentary.
