Well, there you have it. In a recent interview with Huffington Post, Solo: A Star Wars Story screenwriter Jonathan Kasdan opened up about important subtext in the in the new film, which gives new background information of one of Star Wars' most iconic characters.
As the post highlights, while there's been little to no queer representation in the Star Wars franchise, this film is different--Lando appears to be pansexual. When asked in the Huffington Post article whether or not its true, Kasdan said, "I would say yes."
He went on:
"There's a fluidity to Donald and Billy Dee's [portrayal of Lando's] sexuality," Kasdan continued. "I mean, I would have loved to have gotten a more explicitly LGBT character into this movie. I think it's time, certainly, for that, and I love the fluidity -- sort of the spectrum of sexuality that Donald appeals to and that droids are a part of."
"He doesn't make any hard and fast rules. I think it's fun," Kasdan said. "I don't know where it will go."
As Gizmodo pointed out, it's to note that while the writer sees the character like this, there's no on-screen time that totally addresses whether Landon's been in relationships with people who aren't female-presenting humanoids. But there is a moment that acknowledges he might be attracted to droids (and the gender of droids has never totally been addressed).
