The McGuffin in the Tesseract

The McGuffin in this specific movie would that be the Tesseract? Because yeah definitely. But it's it's not interchangeable. It actually does something specific. The modern-day definition is the thing that they want that drives the story. And then every other object since then that people are going for in the various movies and McGuffins too. Yeah I don't even know how you know how useful it is for writers to think about McGuffins so to speak. We're just a McDonald's commercial. Anyway about the Avengers.
