He plays Ser Gregor "The Mountain" Clegane in the HBO series Game of Thrones.
I added my first choices, but feel free to add any other suggestion. Please don't add actors that have already been introduced into the MCU or have already played a character. I'd also appreciate any character suggestions in the comments.
