'Parkland' Trailer: Zac Efron, Billy Bob Thornton & More Star In JFK Assassination Movie

Director Peter Landesman assembled an all-star cast for "Parkland," the upcoming drama about the assassination of John F. Kennedy and its immediate aftermath. Among the famous faces dressed to look like denizens of Dallas in 1963: Zac Efron (as an E.R. doctor at Parkland hospital, where Kennedy was taken after being shot), Marcia Gay Harden, James Badge Dale, Jacki Weaver, Ron Livingston, David Harbour, Paul Giamatti (as Abraham Zapruder) and Billy Bob Thornton. Tom Hanks produced the film, which is based on the book "Four Days In November" by Vincent Bugliosi. "Parkland" debuts at the Venice Film Festival later this month with theatrical release set for Sept. 20. Watch the "Parkland" trailer above. This year marks the 50th anniversary of Kennedy's assassination.
