Biggs will receive $5 million, plus a small slice of first-dollar gross, to appear in Universal's new "Pie" sequel.

KONY 2012 filmmaker Jason Russell's epic freak-out inspired Jason Biggs to reenact the meltdown for laughs -- but not everyone is finding Biggs' parody funny.

Jesse Derris, a spokesperson for Invisible Children -- the advocacy group behind Russell's mega-viral "Stop Kony" campaign -- tells THR, "It's a little surprising that someone would be so cavalier about a serious medical issue just to drum up publicity for a sequel. His last successful movie was 11 years ago, so we're not worried about this one."

In a statement to TMZ, Derris responded with another jab at the actor's celebrity status, asking: "Who's Jason Biggs? Was he famous once or something?"

The American Reunion actor will reprise his role in the latest installment of the comedy franchise, slated for release April 6. Perhaps his spoof was a promotional stunt to get attention for the film -- if so, it's working. In the clip, caught on surveillance camera in the hallways of Chicago's WGN-TV station on Wednesday, Biggs -- who had just done an interview with co-star Seann William Scott -- rolls around on the floor, tearing off his clothes and then running naked.

When security guards arrive at the scene, he puts his pants back on.

Earlier this month, Russell was seen on video having a hysterical naked meltdown in the streets of San Diego; he was arrested for public masturbation and vandalism. His wife, Danica Russell, later explained in a statement that he suffered from "brief reactive psychosis" as a result of exhaustion, stress and dehydration.

Derris declined to elaborate further on Russell's condition.

A representative for Biggs did not immediately respond to THR's request for comment.
