I'm writing a scene for a show where two people sit watching a news report of a murder on TV. The dialogue and action drifts between the people in the room and the news bulletin on the screen. In the bulletin there is back and forth interaction between the anchor in the studio and the correspondent at the murder scene. The scene then occasionally goes live to the studio and to the murder scene. How would you slug line that and indicate change of focus between main location - the lounge with the two people, the anchor live, the anchor onscreen, the corespondent live, with the correspondent onscreen. When they're watching from the lounge I feel like I'm in three locations at once.
