Inspired by the horror film LIGHTS OUTS we look at the use of light on the silver screen, which proves to be a source of madness for the characters of our two selected older films INSOMNIA (1997) and SUNSHINE (2007). In the former, Stellan Skarsgard fights through the disorienting effect of constant daylight to both find a killer and keep his own sins from being revealed. In the latter, Cillian Murphy leads a crew on a quest to reignite the sun to save humanity, while battling increasing philosophical differences with his shipmates. We also discuss pubic hair on screen.
