Hafþór Júlíus Björnsson is an Icelandic professional strongman, actor, and former professional basketball player.
He plays Ser Gregor "The Mountain" Clegane in the HBO series Game of Thrones.
This is just a quick fan cast for a possible MCU Secret Wars saga. Like I say, it was quick, not really that much effort put into it but I feel like this could be a fairly solid cast for the possible next big event in the MCU.
