See actor John C. Reilly and others from "Cirque du Freak" at Universal Studios tonight

Actor John C. Reilly (above left), Chris Massoglia (above right), and Josh Hutcherson will be appearing tonight near the Universal Studios arch at 6 p.m. in promotion of their upcoming film, “Cirque du Freak: The Vampire’s Assistant.”

The movie has inspired its own scare zone at this year’s Halloween Horror Nights 19 which also begins tonight. “Cirque du Freak” tells the fantasy-adventure tale of a boy who unknowingly breaks a 200-year-old truce between two warring factions of vampires. Here’s a trailer for the film, which hits theaters on Oct. 23.
