Macy's has revealed details about a new advertising campaign in the US featuring famous directors and celebrities, launching 16 September.

The ads will feature Sean (Diddy) Combs, Jessica Simpson, Martha Stewart, Usher, Donald Trump, Kenneth Cole, Marc Ecko, Kimora Lee Simmons, Russell Simmons and Tommy Hilfiger, and were directed by directors Barry Levinson, who directed Rain Man, and Bob Richardson, who made The Aviator and JFK.

A 90-second spot will break the campaign during the first hour of the primetime Emmys and will air several times throughout the telecast. 60- and 30-second brand spots will also run throughout the autumn season, the company said. The spots will be available for viewing online from September 19.

"Macy's new brand campaign pairs one of the largest celebrity ensemble casts ever in a TV ad with the incredible filmmaking talent of Barry Levinson and Bob Richardson," said Peter Sachse, president of Macy's corporate marketing.

"With clever storytelling that puts iconic faces and personalities to the assorted collection of brands housed under our one big roof, the campaign unquestionably reinforces Macy's epic heritage and relevance to our customer."
