I saw that rumor, but I'm not sure if I'm buying it. I know I just joked about male Sersi like one page ago, but I don't actually see them doing it. But in case they do, I am sure he would be diverse in some way to make up for the potential backlash due to the erasure of a female character. If not by being gay, then by being POC or something else.
Oh, I was actually just looking up those first reports we got about a gay character, to see if something fits with what we know so far. I think the first report that I saw came from
That Hashtag Show, and it's interesting to look at the description they provided of the character, because it doesn't appear to be the same description we got for the asian male in his 20s. This first report actually describes they were looking for someone of any ethnicity aged 30-49 who physically looked like a superhero. Is it possible that they were actually looking for TWO gay guys, after all? And maybe the older guy was supposed to be the lead, while the other one was his love interest or something? Gosh, I'm even more excited now.
Anyway, if the guy from the website is right about the gay male lead being announced already, I think either Ikaris or Gilgamesh fit the description of the first casting call the most.
The report I read only said he was being considered for the role of an asian gay character, nothing more than that.
