In this scene for Matilda, we see her laying in bed after being told to when she spoke back to her strict father. As we are aware that she is not a misbehaving child and witness the offputting attitudes of her parents, she lays in her bed angry and wanting revenge. Her bedroom begins dark to signify night time yet when she gets an idea the lighting brightens the room and connoting this revelation of what action she should take. It also signifies the change in daytime; speeding up the process of night to day in the film through post-production.
