The Bigfoot found-footage film “Exists” has locked its cast ahead of its Monday start of production for Haxan Films and Amber Entertainment.

Thesps Dora Madison Burge, Samuel Davis, Roger Edwards, Chris Osborn and Denise Williamson go to work next week at Spiderwood Studios in Elgin, Tex. with Eduardo Sanchez (“The Blair Witch Project,” “Lovely Molly”) directing from a Jamie Nash script.

Brian Steele (“Hellboy”) has been set since last year to play the monster.

Producers are Robin Cowie, Jane Fleming, Andy Jenkins and Mark Ordesky with Gregg Hale and Reed Frerichs exec producing.

“Exists,” Sanchez’s first foray into found footage since 1999’s “Blair Witch,” is a horror-thriller that chronicles a group of friends who set out into a remote Texas woods for a weekend of fun and are stalked and hunted by Bigfoot. It’s the second film produced under a multi-picture collaboration between Haxan and Amber forllowing “Lovely Molly,” which bowed at the Midnight Madness lineup at Toronto and SXSW and is being released by Image Entertainment on May 18.

“Blair Witch” took in more than $140 million domestically, thanks partly to a variety of viral marketing campaigns. The film grossed $250 million worldwide.

Sanchez and Haxan Films are repped by APA, Caliber Media and Stuart Rosenthal. Burge is repped by Tag Talent with Davis, Edwards and Osborn repped by Collier Talent. Williamson is repped by Pastorini-Bosby Talent.
