Harry branched out into acting a few years after One Direction broke up. He played Alex in Dunkirk, Christopher Nolan's Oscar-winning war-action movie.

Since then, he has appeared in a range of projects. In addition to the rumored cameo in the post-credits scene of Eternals, Harry signed on to do Don't Worry Darling and My Policeman. So, is he joining MCU?

According to a tweet posted on Oct. 19, 2021, by Matt Donnelly, the senior film writer at Variety, Harry might make an appearance as Thanos's brother, Eros, in the MCU. According to Fandom, Eros is a fun-loving, high-spirited god.

Matt's tweet garnered unprecedented traction on social media, mobilizing "Stylers" and MCU fans just the same. But some responded less enthusiastically — with one person going so far as to angrily proclaim that Matt is bound to lose for leaking the (yet-to-be-confirmed) news. Apparently, Kris Tapley made a similar announcement about Harry joining MCU in a now-deleted tweet back in September 2020.
