When Charles Laughton personally cast Billy Chapin for the role of young John Harper in his 1955 film classic The Night of the Hunter, the boy was already considered an "acting technician" among the child performers of his time. After a private meeting with Billy in his Hollywood home, Laughton told Davis Grubb, the author of the original story: "What I want is a flexible child, and the boy is exactly that." Later, Laughton publicly offered praise especially for "...the strength of [Chapin's] innate ability to understand the construction of a scene, its impact and its importance." Vintage sources claimed that Laughton might find it difficult to direct Chapin, as well as Sally Jane Bruce, who played his younger sister (Pearl Harper), but contemporary sources and rediscovered archival material from the production of The Night of the Hunter prove that, aside from a few intergenerational tiffs, the old man and the boy got along wonderfully, even if, according to these sources, Robert Mitchum, who played the bogus preacher Harry Powell, in fact took over some directing tasks.
