When "Compliance" star Pat Healy signed on to play the role of a man posing as a police officer who manages to coerce a fast food employee over the phone into strip searching an employee, he had no idea that the film would be dubbed the most disturbing of the year.

"We certainly knew we were taking some serious risks and that it was a disturbing movie," he told Fox411.com. "But our premiere at Sundance was our first indication that it was going to be this polarizing lightning rod of a movie."

"People are vocal and they stand up and they scream and they yell," he said. "It surprised me."

Healy plays Officer Daniels, a detached man with a grim character, who calls into a fictional "Chickwich" fast food store. Over the phone, he manages to convince the well-meaning manager Sandra (Ann Dowd) that a female teenage employee has stolen from one of her customers and will need to be strip-searched to help him "find the money." The situation quickly turns into a dark and twisted one that had some viewers storming out of the theater at Sundance.
