"It's difficult to gauge that. With a bad guy you just know you're bad. To play a nice guy is harder - unless you are a very nice person like me of course"

This quote by James D'arcy talks to the problem of playing a great person in a motion picture or tv program. It is a lot easier to play a bad man due to the fact that you can just act out the bad habits. However, playing a great guy needs a certain level of understanding and empathy that can be hard to represent. It is likewise essential to be able to distinguish between a good guy and a hero, as they are not always the very same. D'arcy implies that he is a really good individual, which may offer him a benefit when it pertains to playing a great guy. He is recommending that it is easier for him to represent a great man because he is a great individual in real life. This quote speaks with the value of understanding the character you are playing and being able to bring that character to life.
