To Have and Have Not (film) Hawks would add sexual dialogue and innuendo between Bacall and Bogart. After Hawks and Bogart felt the changes were adequate, Hawks would add one light on the set and they would go through the scene. Hawks would encourage them to move freely and do what felt comfortable for them. After going through the scenes a few times, cinematographer Sidney Hickox would discuss camera set ups with Hawks. According to biographer Todd McCarthy, "To Have and Have Not" is a quintessential Hawks film. It contains classic Hawksian characters such as the strong male and his female counterpart. He also states that
Biphasic and polyphasic sleep one solid block, and he expresses concern that the ways in which the polyphasic sleepers' attempt to limit total sleep time, restrict time spent in the various stages of the sleep cycle, and disrupt their circadian rhythms, will eventually cause them to suffer the same negative effects as those with other forms of sleep deprivation and circadian rhythm sleep disorder. Woźniak further claims to have scanned the blogs of polyphasic sleepers and found that they have to choose an "engaging activity" again and again just to stay awake and that polyphasic sleep does not improve one's learning ability or creativity.
