This drama follows several perspectives around events in Dallas after JFK was assassinated. Among them: the hospital where Kennedy and Oswald were rushed, Zapruder and his famous film, the travails of Oswald’s family, the FBI and Secret Service in the aftermath. It blends a hand-held documentary style and hectic pacing to tell a compelling story. The large cast is peppered with notable actors, including Paul Giamatti, Zac Efron, Billy Bob Thornton and Marcia Gay Harden, and they help focus the impact. This is not a straightforward narrative, but a montage of events. Still, it proves a fascinating (and for me, informative) look behind the scenes of one of the most memorable days in 20th century America.
