Updated January 3, 2019: Sources close to Marvel Studios have offered clarification on previous comments made by studio president Kevin Feige about the presence of a trans character in a currently in-production MCU film, according to Variety.
The Hollywood trade reports that unnamed sources close to Marvel Studios have clarified that Feige's comments, made at a live appearance in response to an audience question, were taken slightly out of context due to the semantics involved in the conversation.
An audience member specifically asked if more "LGBT+" heroes would appear in the MCU soon, "specifically the T - trans."
Studio associates have reportedly clarified that Feige's response - "Yes, absolutely yes. And very soon. In a movie we're shooting right now," were in reference to the presence of a gay character in The Eternals, something Feige previously confirmed, and that there are no plans to include a trans character in any currently in-production films.
Of course, this doesn't rule out the possibility of a trans character appearing in a film that hasn't entered production yet.
Original Story: Marvel Studios President Kevin Feige says that a trans character will appear in a Marvel Cinematic Universe film that is currently in production. Speaking at a New York Film Academy event, Feige said that a trans character would appear in a Marvel movie "soon" - though he didn't specify which film.
“Yes, absolutely yes,” Feige told an audience member who asked if a trans character would play a role in an upcoming MCU project (via Deadline). “And very soon. In a movie we’re shooting right now.”
It's unclear exactly which Marvel Studios films are currently in production. November's Eternals is confirmed to be shooting, while May's Black Widow may still be in production. Likewise, the one-time Fox production New Mutants may currently be undergoing reshoots.
None of the announced actors for Eternals or Black Widow are openly trans, nor are any of the known characters portrayed as trans in comic books. However, Eternals, specifically, has cast several characters with actors whose identities differ from the usual portrayal of their comic counterparts.
Films coming in 2021 that have not been announced as currently in production are Shang-Chi and the Legend of the Ten Rings, Doctor Strange in the Multiverse of Madness, the untitled Spider-Man 3, and Thor: Love and Thunder.
Spider-Man: Far From Home, the film directly preceding the untitled sequel, which is expected to enter production this summer , featured trans actor Zach Barack as the eponymous character Zach, in the minor role of one of Peter Parker's classmates. Far From Home was technically a Sony Pictures production, as will be the upcoming sequel.
Likewise, Netflix's Jessica Jones season 3 featured trans actor Aneesh Sheth who played trans character Gillian on the show - though Jessica Jones was a Marvel Television production, and its MCU-canon status is unclear.
