I mean yeah probably if it communicates who im talking about and why im talking about them. Theres lots of times when ill be talking about an actor and refer to them by the name of their character because i either cant remember or dont know their name, or because its more recognizable for whoever im talking to. But hugh jackman also has other accomplishments that he is known for and that he uses to further his career, its not just him marketing himself as 'wolverine' which is kinda the whole point. If he had never acted in anything else and did livestreams in his wolverine costume and personally sold wolverine merch and had a podcast called wolverine talks then definitely i would call him the wolverine guy. But also acting in a movie is a much bigger accomplishment than being a living meme.
