You know an actor’s done a good job playing a villain when even an off-set look at them makes your blood run cold.For me, that honour goes to Imelda Staunton ― since her role as Mrs Umbridge, I haven’t been able to watch her in anything else without shuddering. I’m always keen to hear about actors who so perfected their part that they had a similar effect on others ― so I was pretty excited to read the responses to Reddit user u/suebustyfriend’s post in the Subreddit r/moviecritic. “Which actor managed to nail being the ‘bad guy?’”, they asked.Here are some of the most-upvoted responses:1) Jack Gleeson as Joffrey Baratheon in Game Of Thronesu/w3stoner“Strongly agree, but what about Iwan Rheon as Ramsay Bolton?”
