"Hi, I'm Lana," the director says with a broad smile and soft, breathy voice, her hair styled in pink dreadlocks.

Lana Wachowski appears in a video introducing the trailer for her new movie, "Cloud Atlas," a drama starring Tom Hanks and Halle Berry — a film on which Lana shares directing credit with her brother Andy Wachowski and "Run, Lola, Run" director Tim Tykwer. But Lana was also introducing herself — as a woman.

The filmmaker formerly known as Larry Wachowski, half of the sibling duo behind "The Matrix" series and "Speed Racer," Lana has been quietly transitioning genders for the better part of a decade.

"Cloud Atlas," which premiered a more than five-minute trailer and a brief, introductory video by its filmmakers on iTunes on Thursday, will be Lana's first feature directing credit under her new name and identity.
