What is the name of the main character in 'The Dead Zone'?

The main character in Stephen King’s The Dead Zone is Johnny Smith.

Johnny is a schoolteacher whose life changes after a serious car accident leaves him in a coma for nearly five years. When he awakens, he discovers that physical contact can trigger visions of the past, present, or future. These abilities make him both a reluctant investigator and an outsider struggling to return to ordinary life.

The title refers to the damaged portion of Johnny’s brain. In the novel, information that remains inaccessible to him is said to be trapped in this “dead zone.” The story follows his efforts to help Sheriff George Bannerman, confront the Castle Rock Strangler, and understand a terrifying vision involving politician Greg Stillson.

A common mix-up is confusing Johnny Smith with Greg Stillson, the ambitious politician whose future Johnny sees, or Frank Dodd, the serial killer he helps identify. Christopher Walken played Johnny in the 1983 film, while Anthony Michael Hall portrayed him in the television series.
