This video was posted on YouTube in 2013 and has had more than 700,000 views. The person claims the video is real and was filmed by a hunter. Here is the video description:
Hunter Frank Wildchild survives attack by large creature in the Canadian wilderness while filming hunting video near Nordegg Alberta, warning shots fired from rifle failed to scare it off, Frank was beaten on the head by this creature and dragged off to a remote shelter high on a ridge, he managed to survive and escaped into the night after creature left him for dead.
I watched the entire 10 minute video and the first thing I noticed was the eerie similarity between this and a Blair Witch type shooting.
If you watch the video there is not much to see and this is something that could easily be faked, which I assume it has been. The supposed Bigfoot is not seen, only some weird noise before he is being dragged off. See for yourself.
