I do believe it was South Park that first introduced characters with their asses where their heads should be, and now comes a similar themed horror comedy called Hellitosis: The Legend of Stankmouth.
From writer, director and producer Robert Mulligan, the film has launched a Kickstarter campaign to help get it finished, and you will find tons of info on the campaign page should you wish to donate. What we have for you below is the films synopsis and a teaser trailer, which looks like a lot of fun.
Basically, the film introduces the horror genre to a new villain, but this poor fella has an asshole for a mouth, so no wonder he is pissed off and wanting to hurt people!
This is a twistedly hilarious story about a non-conventional serial killer! Our killer has a “condition” that has left him a bit shy and embarrassed. No one seems to understand him and everyone seems to be grossed out when they see him …or smell him! …Left with nothing but shame, he resorts to lashing out in the only way he knows how… with VIOLENCE! LOTS OF DISGUSTINGLY FUNNY VIOLENCE!
