Producers from “The Colbert Report” were at Denver International Airport on Friday, taping scenes for an upcoming show on conspiracy theories.

The star of the sarcastic “news” show on Comedy Central, Stephen Colbert, was not at the airport, said Jeff Green, airport spokesman.

Green, being the stalwart communications man that he is, did not want to give away the show’s plot and would only say the crew was there to investigate “conspiracy theories tied to the Denver International Airport.”

A quick spin around the World Wide Web will find plenty of those — that the airport was built by the Illuminati for the New World Order, that its runways form a swastika shape, that the capstone on the floor contains a secret message and that there is a guarded secret highway beneath the airport.

People also have questioned the murals and the large red-eyed Mustang statue at the entrance.

Green said airport officials talked to people from “The Colbert Report” ahead of time to make sure the segment wouldn’t be bad PR.

“If we thought they were going to make the airport look bad we wouldn’t do it,” he said.
