Echo Bridge CEO Michael Rosenblatt (left) and D. Edward Stanley, step-brother to Elvis Presley at a cocktail party in the Palais over the weekend in Cannes. The small gathering to hear about the new film "Riding with Elvis" from the writer/director/producer, is recounted with Southern charm and a smile. As Elvis' younger step-brother, Stanley dropped out of high school at 16 to tour with the King. Four years ago, Edward Stanley decided to write about his experience and set out to tell the story "no one's ever heard" of what he calls "his Elvis."
