Only three films have ever won the “Big 5” Oscars: Actor, Actress, Screenplay, Director and Film. And this is where we’d usually tell you their titles (with links). But let’s keep a sense of mystery this time and reveal them as we go. We’ll tell you now that they’re from the Thirties, Seventies and Nineties. The rest is up to you (no Googling!) Our special thanks to listener Natasha Broadstock for suggesting this topic.
