Precious and soon-to-be The Paperboy director Lee Daniels did an interview with 'The Georgia Voice', an LGBT media outlet, in anticipation of his attendance at the 24th Annual Atlanta HRC Dinner on May 14th. The article briefly mentions The Paperboy (highlight for potential spoilers):
Daniels' next project is “The Paperboy,” which is based on the novel by National Book Award-winner Pete Dexter. Daniels describes it as “a love story between two brothers,” where one learns to accept that his brother is gay.
From what I understand, I think Ward is the latter. ETA: The Paperboy is Jack, the younger brother, and that is who Zac is expected to play. It is unclear who is playing older brother Ward, but based on age, my personal guess is Tobey.
Zac was reportedly at WB
E! Online's Marc Malkin posted a tiny blurb on the LAFH Awards:
That was Zac Efron on Thursday at the 2011 L.A. Family Housing Awards at the Music Box Theatre, where he mingled with event chair Warner Bros. exec Blair Rich and actress Cody Horn, among others.
As jeezbee pointed out in comments, Zac was actually on the event committee for the awards alongside WB marketing exec Sue Kroll, The Lucky One producer Denise Di Novi and event chair Rich. Cody Horn is not just an actress but also daughter of Alan Horn, former WB President and COO.
