The Wachowski brothers are the filmmakers who created "The Matrix" trilogy, but the duo will now just be known as "The Wachowskis", dropping the "brothers" part of their name. Why? Because Larry has been undergoing hormone therapy, psychological counseling and has completed the operations to become Lana Wachowski. They are currently working on the film "Speed Racer" and rumor is that the press shy duo may talk to the media after the filmming is complete.
Here is a picture of Larry when he began taking the hormone therapy a few years ago
