Sears' Superman World Record Set After More Than 500 Employees Dress As Man Of Steel (PHOTOS)

They weren't faster than a speeding bullet or able to leap tall buildings in a single bound, but the more than 500 Sears employees at the company's suburban Chicago headquarters were — as of Wednesday — record breakers.

In all, 566 employees Sears employees gathered at the company's Hoffman Estates headquarters to shatter the Guinness World Record for the largest number of people assembled in one place dressed as Superman, according to NBC Chicago.

According to Business Insider, the previous record for a group of people dressed up as Superman was 437.

To qualify, each costume had to feature red boots, a blue bodysuit, a yellow belt, the signature Superman "S" and a red cape, Guinness World Records adjudicator Philip Robertson told the Daily Herald at the event.

Setting the record was one of the several publicity events staged by Sears in advance of the hotly-anticipated "Man Of Steel" blockbuster. The company teamed up with Warner Brothers, the studio behind the "Superman" reboot, ahead of the June 14 release.

Sears plays a prominent role in the film, according to ABC Chicago.

"The movie will feature Kenmore and Craftsmen product. Superman's father uses Craftsman Tools and works at a Sears," said Ron Boire, executive VP of Sears and K-Mart. In different versions of the Superman mythology, the Man of Steel's earthly father Johnathan Kent is a farmer and alternately the owner of a general store.

Former Chicagoan Michael Shannon plays villain General Zod in the new movie, though the "Man of Steel" has other Chicago connections as well. Filming was done both in Chicago — The Chicago Board of Trade and the Sears Willis Tower were used as interiors and exteriors for The Daily Planet — and west suburban Plano was the filming location for Smallville.
