My movie collection contains a wide variety of films, but I have quite a few that explore post-apocalyptic or futuristic dystopian worlds. I find these kinds of stories fascinating because they offer a glimpse into potential futures and also provide commentary on our current society and the direction we’re headed if we continue on certain paths. What Happened to Monday falls in line with films like Blade Runner, Total Recall, Equilibrium, and Children of Men. The film is set in a future where dwindling food resources due to overpopulation have led to a strict one-child policy enforced by an organization that freezes any subsequent siblings until conditions improve. Terrence Settman (played by Dafoe) finds himself in a difficult situation when his granddaughters—sextuplets—are born, their mother dying during childbirth. He names them after the days of the week and makes the risky decision to raise all seven of them in secret, taking precautions to keep their existence hidden. Once the girls reach an age where he feels they understand the dangers outside and the consequences of exposure, he allows each one to go out on her designated day – Monday goes out on Mondays, Tuesday on Tuesdays, and so on. They live their days as a single person named Karen Settman. As with any group of children, the girls develop distinct personalities—some are shy, others rebellious. The most defiant sister causes serious problems for the others when she ventures out on an unscheduled day and suffers a painful injury. Thirty years later, the sisters have successfully maintained their secret lives, developing individual interests while working together to keep up the Karen Settman persona through nightly briefings about what happened during that day’s outing. Everything goes smoothly until Monday disappears, leaving her sisters worried and Tuesday suddenly losing her sight, unaware of recent events. It then becomes their responsibility to discover what has happened to Monday. What I appreciate most is the film's core idea—this is why I enjoy dystopian stories in general. The genre can explore any scenario that could lead to a dystopia, whether it’s overpopulation leading to restricted breeding or suppressing emotions to prevent conflict and war. I was also impressed by Noomi Rapace and Clara Rosencrantz's performances as the sisters at different ages. Playing seven distinct personalities required considerable range from both actresses to capture the essence of each sister while also portraying Karen. The way the film juxtaposes the characters when they are together is another strength, done in a sophisticated manner that avoids cheapness or cheesiness.
