Marvel boss Kevin Feige says some Phase 5 cameos may never be seen again, while others may be like The Incredible Hulk's Tim Blake Nelson and take 17 years to return: "It's about finding what the right moment is"

Clea in Doctor Strange in the Multiverse of Madness.

The MCU is guilty of not always tying up its loose ends. Marvel Phase 5 featured several cameos, particularly in its post-credits scenes, that seem like they won't have any payoff – for example, Charlize Theron's Clea from Doctor Strange in the Multiverse of Madness, or Harry Styles' Eros in Eternals.

And it looks like that could be an accurate prediction, as Marvel Studios president Kevin Feige says that some of these characters may never be seen again – but some may also reappear eventually, even if we have to wait 17 years.
