Grillo has also stated that something involving Crossbones will apparently be happening in the MCU at some indeterminate point in the future.
Grillo never actually stated that he was part of whatever was happening, and his comments to Metro now confirm that the actor has no expectation of reprising his MCU role at this time.
Frank Grillo has previously made it clear that he would love to see Crossbones return to the MCU, and the fact that these are comic book movies certainly, in his eyes, opens up an opportunity for the character to return if and when somebody decides to do it.
It’s far from uncommon for an actor’s comments to taken out of context or blown out of proportion over time as the internet game of telephone gets played with every statement.
