I don’t want to bash Daishen Nix. I have nothing against him personally, but he seems to be an example of typecasting gone badly wrong. Sometimes one reads about the “first choice” person to be cast in a movie, who didn’t end up playing the part, and the person who did, way down the list, made the role iconic.
To use an example probably everyone knows, Harrison Ford wasn’t first choice to be Han Solo in the original Star Wars movie. Others considered ahead of him were: Al Pacino, Burt Reynolds, Sly Stallone and Kurt Russell. Those guys are hard to imagine in the role, but they sort of fit the idea of the part.
