Could we be seeing Crossbones reappear in the next Avengers movie? According to Frank Grillo we will see Crossbones again very soon.
At the 19:06 mark in the the latest episode of the UFC Unfiltered podcast, the death of Crossbones in Captain America: Civil War is brought up and Frank Grillo says:
“He makes an appearance in the next Avengers movie, but it’s a flashback.”
He says he can say whatever he wants because he’s never doing a Marvel movie again. Later in the podcast he said he doesn’t watch Marvel or Star Wars movies, but he did like Captain America: The Winter Solider.
If Crossbones is appearing via a flashback in Avengers 4, it’s probably not much of a big role and it could even just be existing footage being reused. Still, it’ll be cool to see the character on screen again if this is true.
