Who didn't "look" the part but totally owned the role?

I recall in Star Trek TNG episodes Patrick Stewart was not revered due to not looking like Pike or Kirk, to where his wig was flown in, and many objections in season 1. Now it seems he is widely acclaimed as Picard.Nowadays I see your average clickbait post of this person looks like this character and therefore would be perfect.But my assumption is shouldn't the actor fit the character rather than just be a look alike?Are there good examples where someone who totally looks the part plays badly or has bad chemistry with the others, or someone who looked different from the norm convince you they fit the character in performance? via /r/movies https://ift.tt/31eda65
