The assassination of President John F. Kennedy is one of those days that will forever remain in the minds of the American people. And though everyone knows the story of what happened when JFK was shot (unless you’re a conspiracy theorist), many aren’t aware of what happened immediately after the president’s brutal murder. Enter Parkland, which promises on its poster a portrayal of “the JFK assassination as you’ve never seen it before.” The film centers on the events at Dallas’ Parkland Hospital, where Kennedy was taken after being shot, and is based on the book “Four Days in November” by Vincent Bugliosi. These stills, courtesy of Yahoo! Movies, depict some of the principal characters tasked with taking care of the dying president — and even the one responsible. Paul Giamatti steps behind a camera as Abraham Zapruder, the cameraman who captured the only known footage of the assassination, while Jeremy Strong is a dead ringer for Lee Harvey Oswald, Kennedy’s killer. Billy Bob Thornton is a terrifying-looking secret service agent and just a generally grumpy-looking man who rushed to Kennedy’s side after the shooting. Zac Efron is interestingly cast as Dr. James Carrico, who tended to Kennedy upon his arrival at the hospital. I won’t judge too harshly before seeing his performance, but Efron, you always look 15 and flustered, kid. Marcia Gay Harden, as Nurse Doris Nelson, looks terribly worried, but you can imagine that she’s just seen some shit. Take a look after the break.
