An official selection of the 2014 Los Angeles Film Festival, this HBO Films presentation is a fascinating portrait of one man's descent into the delusions of a fractured mind. Told with incisive imagery, energy and humor, Nightingale is a compassionate depiction of isolation in the midst of a world ruled by social media. David Oyelowo gives a spellbinding, roller-coaster ride of a performance as Peter, the sole character in the film, a war veteran who lives in a nondescript ranch home with his mother, and shares an ongoing monologue with himself, and the audience, via his laptop computer's video recorder.
