Yesterday we told you about a Spanish-language film that's about to make its premiere at the Slamdance Film Festival later this month. It's called 'Atrocious,' and based on early buzz folks are calling it the next 'Paranormal Activity' -- partly because of its "found footage" angle, and also because it's scaring the hell out of people.

Those of you who followed 'Paranormal Activity' will remember that it premiered at Slamdance first before being snatched up and put on a shelf for two years. That's when Paramount took a chance on it-- staged a brilliant marketing campaign -- and the rest is history (part three is already in the works). Will 'Atrocious' become that next tiny festival horror movie to cause major waves around Hollywood? We're not sure yet, but we bet a lot of people will be keeping their eyes on it when it premieres next Saturday night at the top of Main Street in Park City, Utah.

In advance of that premiere, Cinematical has been handed an exclusive new trailer for the film, which marks the directorial debut of 27-year-old Mexican filmmaker Fernando Barreda Luna. Check it out after the jump and let us know what you think.
