The One Secret You Never Noticed In The Matrix

In fact, the real secret is the Wachowski’s hired identical twins specifically for this scene, and gave them identical hair cuts and clothing to create the illusion of duplicate ‘character models’. This is because they reasoned that Mouse would have been lazy in the programming of that particular, hastily put together exercise and would merely copy and pasted dozens of lines of the same code. This resulted in duplicates within the same scene.

After all, only anyone ever cared about was the girl in the red dress...

Remember when we talked about every frame serving the narrative? These duplicates not only serve as an easter egg to those hyper-nerds who comb each frame for details, as well as adding depth to Mouse’s character, the capabilities of the resistance, and the Matrix on a whole, and but also make the world feel more synthetic to the viewer, even on a subconscious level.

It’s the details like this that make the simulation Neo is in begin to feel… wrong. We start to feel boxed inside, with cracks appearing in the world around Neo as the reality Matrix becomes apparent to him, and us: it's a digital cage.
