I just watched the new King Arthur movie and I liked the guy who played Arthur a lot. He had this "I am the boss around here" demeanor at all times. He reminded me of someone.

Sure enough. I looked up the movie on IMDB and it turns out the lead guy spent weeks watching clips of Conor McGreggor on YouTube to adapt his demeanor. He did a great job of it too. He had his swagger down and everything.

I had not considered doing something like this until now, but it sounds like a fun challenge to embody in yourself the style of someone people view as a badass.

Has anyone done this? And if so, who did you look up to for it?
