Larry Wachowski Transgender: 'Matrix' Director Reveals Transition To Lana Wachowski (VIDEO)

The director of "The Matrix" and the highly-anticipated film "Cloud Atlas" has become the first major Hollywood director to publicly come out as transgender.

Lana Wachowski revealed she has transitioned while promoting her new film, the New York Post reported.

Lana has been transitioning for years now, the Post also reported. This new clip for "Cloud Atlas ," starring Tom Hanks and Halle Berry, appears to be her first public appearance since transitioning.

In the trailer, Lana introduces the film with her brother, Andy Wachowski, and director Tom Tykwer.

"Hi, I'm Lana," she says with her hair styled in pink dreadlocks.

Lana's personal life has been a source of headline fodder for years now.

In 2002, Wachowski was going through a bitter divorce from wife Thea Bloom, as People magazine reported at the time. In 2003, a date Wachowski took to the Cannes Film Festival told the British tabloids that the director was a "cross-dresser."

That same year the Gothamist reported on a column written by movie journalist Dave Poland, alleging that Wachowski was in the process of undergoing a "sex change" .

"Every indication I have says that Larry Wachowski is now in the process of changing his sex," Poland wrote. "Dressing in public like a woman, taking female hormones and yes, having a sex change operation."

Other public figures have transitioned under the microscope of public scrutiny.

In May, Against Me! singer Tom Gabel came out as transgender to Rolling Stone and announced plans to start living as a woman, Laura Jane Grace.

Grace is still married to her wife, Heather, with whom she has a daughter.

"For me, the most terrifying thing about this was how she would accept the news," Gabel said. "But she's been super-amazing and understanding."
