In what's being dubbed a tribute to openly gay actor George Takei, the upcoming Star Trek Beyond will indeed reveal that Hikaru Sulu—the role originated by Takei and currently being played by John Cho—is gay and has a child via that same-sex partnership. This may not seem like a huge deal for such a progressive franchise as Star Trek, but it's pretty groundbreaking stuff, even in 2016.
While speaking with the Herald Sun, Cho said that the idea came from director Justin Lin and co-writer and co-star Simon Pegg, who approached the actor with the idea. “I liked the approach, which was not to make a big thing out it, which is where I hope we are going as a species, to not politicise (sic) one’s personal orientations,” said Cho.
Again, this doesn't seem like it should be such a big deal, but even Star Trek has never featured an openly gay crew member. I'm sure some book I've never read or some episode of some YouTube series has a whole ship full of gay characters, and that's great, I'll totally get to all of those some day, but to the casual fan, this is kinda huge. I'm glad that Gene Roddenberry's vision of a unified future wherein petty shit like race, religion, and sexuality doesn't matter one bit. It's about time, Star Trek, but it's also better late than never. Kudos to Cho, Lin, and Pegg, which incidentally sounds like a pretty awesome law firm.
