“All Hail the King” was the glorious @Marvel One-Shot attached to the release of Thor: The Dark World a few weeks ago. Writer and director Drew Pearce confirmed something that I had noticed upon my viewing. There is only one inmate (portrayed by Allen Maldonado) noticed in the film who has a Marvel history.
He is named Fletcher Heggs or known to others are the Knight.
He is a pawn of Obdiah Stane and has a long history as an Iron-Man villain. Pearce warns that we should keep an eye out for the character as we move forward in the MCU.
