Marcia Gay HardenZac EfronBREAKING: Zac Efron and Marcia Gay Harden have joined Paul Giamatti, Billy Bob Thornton and Jacki Weaver in Parkland, which Peter Landesman wrote and will direct based on Vincent Bugliosi’s book Reclaiming History: The Assassination Of President John F. Kennedy. The film is produced by Playtone partners Tom Hanks and Gary Goetzman and also is being produced and financed by Exclusive Media and its co-chairmen Nigel Sinclair and Guy East.

Bugliosi’s mammoth book, which Playtone and Landesman originally set up at HBO, refuted the conspiracy theories surrounding the assassination that were embraced in the Oliver Stone-directed JFK. The film does not address the conspiracy aspect and focuses only on what happened at Parkland Hospital in Dallas on the day Kennedy was assassinated on November 22, 1963. The film, to be shot in Austin, is destined for a 2013 U.S. theatrical release around the 50th anniversary of the assassination.
