However, Frank Grillo made it clear that he doesn’t want to return to the MCU, as there’s nothing else meaningful for him to do in this franchise, and he’s ready to exit “the party.”
That said, there’s still a slim chance that Crossbones could have been included in a future Marvel movie.
So for those of you who were nursing a glimmer of hope for more Crossbones in the continuously growing MCU, extinguish it now.
After all, with Thanos coming soon with the power of the six Infinity Stones at his disposal, maybe he could have been resurrected.
