A 1974 film adaptation was directed by Peter Bogdanovich, with Cybill Shepherd as Daisy, Barry Brown as Frederick Winterbourne, Cloris Leachman as Mrs. Ezra Miller, Duilio Del Prete as Mr. Giovanelli, and Eileen Brennan as Mrs. Walker. Frederick Raphael wrote the script; the film follows the structure of the original story without significant changes, and even uses portions of James' dialogue from the novel.
A rap adaptation of Daisy Miller appears on Heavy Jamal's album Shining Sky Lobster.
