The name of the character in The Hamlet who is the younger brother of the characters Binh and Mai. The boy is later informally adopted by Sergeant Jay Bellamy and taken to live in St. Louis with the sergeant and his millionaire parents. The narrator refers to the child actor playing the role by his character’s name because he can’t remember the boy’s actual name. The young actor is the scion of a Filipino acting family. His mother pampers him on the set and tells the narrator that her son, who also sings, is destined for Broadway. He wins over everyone on the set by singing “a high-pitched version” of the song “Feelings.” The young actor’s mother notes how he can pronounce the “F” in “feelings” due to lessons in elocution. The only person working on the film who doesn’t like Danny Boy is James Yoon, due to the child actor’s tendency to upstage other actors. Danny Boy mimics the Thespian by insisting on staying in character at all times.
