"Playing a robot is possibly the most difficult role you can have as an actor, because you have to take all your innate emotional responses and completely suppress them. Even the way you walk is affected"

This quote by Kristanna Loken speaks to the trouble of playing a robotic as an actor. It needs a lot of control and discipline to reduce all of one's natural emotional reactions. This is particularly true when it comes to body movement, as even the way one walks can be impacted. It is an obstacle to represent a robot in a persuading way, as the actor must be able to convey the character's robotic nature without relying on any of the usual psychological cues. It is a difficult task, however one that can be rewarding if done properly. Playing a robot requires a good deal of focus and dedication, as the actor should be able to totally reduce their own emotions in order to properly portray the character.
