Broadway has made no secret of casting Hollywood A-listers in the past few years in an effort to fill more seats, and tomorrow the Great White Way will be getting two particularly prestigious patrons. If all goes to plan, President Obama and First Lady Michelle Obama are set to attend the 8 PM performance of the revival of A Raisin In The Sun at the Ethel Barrymore Theatre. The president will be in NYC earlier in the day on official biz. This latest version of the revered 1959 Lorraine Hansberry play stars Denzel Washington in the Oscar and Tony winner’s first return to Broadway since 2010′s Fences. The Kenny Leon-directed and Scott Rudin-produced play sees A Raisin In The Sun return to the very theater where it first opened more than 50 years ago. Having had previews last month, the play — which is set on Chicago’s South Side, where the Obamas have a home in the upscale Kenwood neighborhood — opened on April 3 to a limited engagement that sees it running just to June 15. I’m assuming the Obamas, who will be heading back to D.C. after taking in the show, didn’t have to pull too many favors to get tickets to the nearly sold-out run. But with a hot commodity like this, it helps that they know people.
