John Reese is a
fictional character from the
CBS crime drama television series
Person of Interest. He is played by
Jim Caviezel. Reese is an intense, solitary man whose dry sense of humor emerges over time. He speaks in a low, calm and confident voice, despite the fact that people are almost always after him or the people he is protecting. He works with
Harold Finch, a reclusive private billionaire software genius, to help residents of New York who are potentially involved in violent crime. Intensely grateful to Finch for, in Reese's view, having saved his life, he regards Finch as his only friend. Extremely skilled with a range of weapons and hand-to-hand combat techniques, Reese is nonetheless possessed of a level of humanity that drives him to work with Finch to protect potential victims of violent crime. Reese owns Bear, a
Belgian Malinois he rescued from white supremacists and sent to live with Finch to assure Finch's safety.
