Artie Lange's Beer League [DVD] [2006]

Concentrate and try to be the best in this physics puzzler

When the father of a sizeable family has an affair with a woman (Arisa Will) who is - unbeknownst to him - a powerful practitioner of the occult, but later rejects her, his entire family is soon wiped out in a disgusting bloodbath that baffles everyone. Thus begins Art of the Devil 1 (aka Khon len khong), a Thai horror film from neophyte director Tanit Jitnukul (Kun pan, Andaman Girl). When an investigative reporter looks into the case and becomes convinced that the aforementioned mistress wields the hand of Satan, he unknowingly opens the door to a violent supernatural battle that literally rips his loved ones apart, as the witch sends eels bursting from human stomachs and rips babes from the womb.
