Cusick added that the experience really brought to light just how big the MCU is for him, which begs the question to whether or not Cusick could’ve potentially spoiled something regarding another Marvel property.
Henry Ian Cusick tells Screen Rant he learned that the hard way, shortly after confirming a few details to press regarding his character in Marvel’s Inhumans.
Cusick says Marvel contacted both his agent and manager very quickly, and informed them that Cusick must be very careful of what he says about his character and how he relates to the MCU.
That’s purely speculation, but it seems like an odd statement to make in the middle of explaining how he has to be careful about what he says.
