They Call Him Sasquatch (2003)

"Fifteen strangers will set out to prove the existence of a legend... all they need to do first is survive each other."

They say Bigfoot doesn't exist. But try telling that to a misguided group of explorers (including Garry Marshall and Warren Berlinger) who are determined to track down the mythical Sasquatch when he's spotted in Northern California. The stakes get even higher when a privacy-loving pop star with a penchant for exotic animals offers up an impressive cash prize. But will the competing hunters kill each other first?
