MacGuffin

Hitchcock perfected the MacGuffin as a narrative device, using seemingly important plot objects to drive suspense while the real tension lies in character psychology and the audience's emotional investment.

The Coen Brothers consistently employ MacGuffins like the briefcase in Pulp Fiction and the ransom money in Fargo, where the pursuit of the object matters less than the chaos and human drama it generates.

Tarantino's films are built around valuable but ill-defined MacGuffins—the briefcase in Pulp Fiction, the bingo cards in Inglourious Basterds—that serve as narrative anchors while the real story unfolds through dialogue and character interaction.
