I have had this memory of a movie for as long as I can remember but have never been able to find it. Most likely late 90s early 2000s. I’m not sure if it was a fever dream or what, but the only scene I can really remember is this.

It involved a guy in a suit, like a Barney the dinosaur suit, in the stall of the bathroom on set of wherever he was shooting. The main character looks over the stall and sees the guy without his costume head on and it’s some grotesque hillbilly guy. I’m pretty sure the guy in the costume was luring kids to the show to murder them or something but am not positive.
