Television is playing the part of one of the characters on a TV series. Trained and talented actors makes us be addicted to all these amazing TV series that keeps us a wake when for sure we know that we have to be at work the next day!
Television programs are built around commercial breaks, and to make sure you don’t change the channel, that’s when the victim tells the detective they know who the killer really is. A dramatic pause, music cue, and the camera slowly inches closer to the detective’s astonished/puzzled/worried face. Cut to commercial. That’s acting for television – lightly exaggerated. While today’s shows are much more grounded, casting directors can still identify actors who only have television experience.
