Of course there's a movie. This is a great tragic story; how could Hollywood pass on that? There was a version created for TV back in 1960, but the 1993 version is rated PG and available on Netflix. Buyer beware: One Washington Post reviewer said they "have made watery gruel [you know, the stuff Oliver Twist had to eat at the orphanage] of Edith Wharton's popular 1911 novella" (source). Let your students be the judge.
