A man is kicked in the face a bunch of times
Despite the "some violence" in the R rating description the violence in this film can be quite gory and shocking, especially for a comedy.
Mostly in a funny or comical fashion but for a comedy it is pretty graphic and bloody
A machine falls on top of a cashier, killing her instantly. A large amount of blood and gore splashes onto a wall
A massive earthquake then opens up the ground near a mansion where a large party is taking place, creating a portal to what is presumably hell. Dozens of party goers walk outside and are sucked into the crater. One person grabs onto the foot of someone who is on land, and the man then kicks him down. A bloody, severed hand is visible. A woman's head is accidentally crushed by a fleeing party goer, with blood briefly shown spurting.
Another person is impaled by a lamp-post, with massive amounts of blood spurting from his chest as he expresses bewilderment. Very graphic and gory.
A man is raped by a demon (offscreen) and becomes possessed, attacking his friends with his new found supernatural strength before being subdued and tied to a bed. He is ultimately burned to death after a fallen candle triggers a massive fire within a mansion. The mansion collapses on him and we briefly see blood splash on the ground.
A man attempting to break into a house is beheaded by a demon, his head falls through a hole in the barricade and the resultant bloody mess causes the occupants to unintentionally kick his head around like a soccer ball. There is blood all over the floor. A man picks the head up and blood pours out of the stump. Very graphic and gory.
A man is eaten alive by the gang of cannibals. Blood is seen spurting in the distance and his severed nose is briefly seen.
A man is struck in the nose with the axe handle due to a misunderstanding.
