Frequent depictions of cigarette smoking and alcohol consumption occur throughout the film, primarily by the adult male characters. Alcohol (whiskey and brandy) is often shown as a coping mechanism for grief and during social discussions, with some scenes featuring visible intoxication and slurring. There are also specific depictions of characters smoking cigarettes and marijuana (cannabis) in social or "bohemian" settings, particularly during sequences exploring the characters' pasts. The use is portrayed realistically within the context of the film's mystery and dramatic themes.
