Production for “The Matrix 4” is fully underway.

In new fan photos from the San Francisco set, Keanu Reeves, Carrie-Anne Moss and writer-director Lana Wachowski, have been spotted getting back into character, as Neo and Trinity 17 years after the last franchise installment.

While the photos show Neo… we mean Reeves, grabbing a cup of coffee, the images are still sending fans over the edge, with many still wondering what is actually in store for “Matrix 4”. Warner Bros. has yet to reveal any specifics.
