Due to Disney's acquisition of Fox, coupled with the launch of the streaming platform Disney+, the future Marvel Cinematic Universe will have a very complete change.
One of the changes is that the copyright to the X-Men characters that have been out for many years is finally returning, and the Marvel Cinematic Universe will have a large wave of new members joining.
Although Kevin Feige has said that Marvel will not continue to develop X-Men movies for a long time, the related casting news has been endless.
PinkNews quoted We Got This Covered as saying that Marvel executives "very much wanted" to invite Shea LaBeouf to star as the gay "Iceman."
It is said that this is because LaBeouf has been focusing on small-budget movies since "Transformers" and refused to take on blockbusters, so Marvel believes that a gay superhero may be able to impress him and make him return to blockbusters.
As for the character of "Iceman", it was indeed heterosexual in the previous X-Men series of movies, but in the 2015 "All-New X-Men" comic, the young Iceman has come out, so the current Iceman is LGBT superhero.
For this rumor, several members of the LGBT community have expressed their rejection, hoping that Marvel will find a real gay actor to play the role. But after all, this is still just a rumor, and it is still early to determine the actor.
