“The first building block of any Indiana Jones movie, according to Lucas, is something called the MacGuffin. The term, popularized by Alfred Hitchcock, refers to an object or goal that kicks the story into action and drives it to the third act. Hitchcock held that the less specific the MacGuffin the better. In his 1959 suspense classic, North by Northwest, the men chasing Cary Grant are after microfilm containing “government secrets”—that’s all the audience learns about why the film’s villains cause the hero so much trouble—and Hitchcock considered that to be a perfect MacGuffin, because it was so wonderfully vague.” [Spoiler on page four.]
