John Cho is about to go where no Star Trek character has gone before.

When ET spoke with the actor on the set of Star Trek Beyond, he said we would meet Sulu's heretofore unknown daughter in this installment. Cho also teased "another revelation," but said we would have to "wait and see the movie." Turns out, we don't -- Sulu is gay!

"I liked the approach, which was not to make a big thing out it," Cho told Australia's Herald Sun. "Which is where I hope we are going as a species, to not politicize one's personal orientations."

Yes, Sulu will have both a daughter and a husband in Beyond -- a change in canon inspired by George Takei, the original Sulu in the 1960s TV series, who is gay and a vocal advocate for the LGBT community.

It's safe to say fans are pleased:

Cho previously told ET that Beyond, which hits theaters on July 22, kicks off with the crew of the USS Enterprise feeling "homesick."

"Sulu has a heartache for his little baby. [He] had brought his picture to his console, which technically, we've been saying, it's unprofessional. It's in the way of the buttons," Cho explained, adding of his on-screen daughter, "She's a cutie. I got it out of a picture frame from Walgreens."

Star Trek Beyond also marks the 50th anniversary of the franchise. When ET spoke with the cast on the movie's set, we found out how the film will pay homage to the original. Get the scoop in the video below!
