It took until this year for Captain America: Brave New World to finally address the half-risen Celestial in the room, but that's honestly the closest the MCU has come to acknowledging the events of Eternals. It's hardly a surprise, really. In the post-Avengers: Endgame era, the movie was the first major misfire from Marvel Studios that, according to one of its stars, had a whole blueprint mapped out that never came to fruition.
During an appearance on the Working It Out podcast, Nanjiani revealed just how much he'd committed to before the film's release, and the shock he experienced when it didn't receive the warm welcome like the other MCU movies that predated it. "It came out, it got really bad reviews, and it didn't do that well. It shattered me too much," the actor who played Kingo confessed. "That was when I was like, 'Oh, I need to go to therapy to figure this out.'"
