Though it seemed like Ti West would follow 'The Innkeepers' with the sci-fi flick 'The Side Effect' starring Liv Tyler, the director has a third act twist of his own: West will direct 'The Sacrament' next, and he's got fellow horror director Eli Roth on board to produce.

Ti West famously directed -- and then disowned -- 'Cabin Fever 2,' the direct-to-DVD sequel to Eli Roth's breakthrough horror hit. And according to The Playlist, the pair are teaming up for the new film 'The Sacrament,' which West will direct and Roth will produce for Worldview Pictures. Perhaps taking a hint from his pal Quentin Tarantino, 'The Sacrament' will have the "Eli Roth Presents" tag attached.

There are no details about the plot at this time, but we know it's a horror/thriller and the title seems to suggest a religious connection. Filming begins in Georgia next month, so a premiere at SXSW in 2013 seems likely -- the fest also premiered both 'The Innkeepers' and 'The House of the Devil.'

Worldview Pictures is also producing Roth's 'The Green Inferno,' his highly-anticipated return to the director's chair. That film's title is inspired by an alternate title to Ruggero Deodato's 'Cannibal Holocaust,' which suggests a cannibal plot of its own.
