Read first, or watch first?
Book first, by simple arithmetic: the title story takes fifteen minutes to read aloud and the films are genuinely hard to find, so the page is the version your family will actually meet. If the 1974 short or the Oscar-nominated Selfish Giant ever crosses your path — a library DVD, a classroom archive — both are gentle, faithful, and worth the detour. The one thing to know cold: the 2018 The Happy Prince on streaming services is Rupert Everett's R-rated film about Wilde's final years in exile. It is not the fairy tale, and it is not for kids.
