Script – the written text of a play, film, or broadcast.

Screenplay – the written text of a film, including acting instructions and scene directions.

While both words are used interchangeably, a script typically features character dialogue and stage directions, while a screenplay includes other production or story details that might happen off-camera.

The Social Network has one of my favourite scripts of all time, written by Aaron Sorkin. From the opening scene, Sorkin uses dialogue to allow the audience to fully understand the characters’ ambitions, insecurities and personalities, and also engage with the satisfying flow of each character’s lines. By going in-depth on the characters, he expertly manages to evolve them and write the story of how the insecurities and personality traits led to the creation of Facebook, and the relationships and legal troubles along the way.
