There isn’t really anything fresh about this movie. Everything in it has been done a billion times, but it was compelling and silly enough to keep me interested. As far as clown movies go, it is funnier than Patch Adams but less funny than It. All three movies have dead kids though. So there’s that.
A guy finds a haunted clown suit, which he dons in order to amuse a battalion of annoying brats at his son’s birthday party. BAM: He’s cursed.
As explained by the Wise Elder character, Peter Stormare (the guy who feeds Steve Buscemi into a wood chipper in Fargo), clowns were originally not balloon sculpting ding-dongs, but cave dwelling Nordic demons who would feast on children. The costume is haunted and infested with demonic energy. Stormare even has a leather bound ancient text complete with Guillermo del Toroesque clown monster sketches, so you know he’s legit.
Dude can’t get out of the clown suit; it’s bonded to him like the Venom symbiote or the Goosebumps haunted mask and it is slowly transforming him into the Icelandic variety of Bronze Age kid-munching clowns. The only way to get him out of the suit/stop the clown-demon is to chop his head off or let him eat five children. Once he gets started munching on kids, you’d think they would just let him finish, but the other characters are committed to decapitation despite the pileup of child corpses.
To the guy’s credit, he tries to decapitate himself, but he quits trying once he realizes how fun it is to eat kids. Once the dust from the exposition settles, the rest of the movie is pretty typical possession/demon/slasher stuff that borrows from other popular killer clown stories: He has the fangs of It, but none of the one liners; he has the charisma of Gacy, but none of the sodomy; he looks just like a juggalo, but doesn’t dump Faygo all over himself or rap about titties.
The origin story of the actual movie is more interesting than the clown mythology in the film itself. A couple of guys made a fake trailer for this movie with no (clear) intention of ever filming the thing. In their mock trailer, they start with “From Master of Horror, Eli Roth…” which I guess flattered/interested Roth enough to track these guys down and invite himself on board as the producer. No one probably thought of this movie as “theirs”; the trailer-makers probably thought their inside joke got scooped up as Roth’s new pet and Roth probably thought his semi-pandering to internet horror nerds and attachment of his name would be enough of a contribution. What emerges is a pretty “meh” horror movie with some cool cinematography and make-up that follows a played out formula.
