November will run through Nov. 4 under the direction of Scott Zigler, who staged Mamet's The Old Neighborhood on Broadway. It officially opens Oct. 7.

"Set just days before a major presidential election," original Broadway press notes state, "November involves civil marriages, gambling casinos, lesbians, American Indians, presidential libraries, questionable pardons and campaign contributions."
