Ryan Coogler shared that the story of the twins, Smoke and Stack, was comprehensively developed well before filming began, providing audiences with a deep Ryan Coogler Sinners backstory. In a discussion on Proximity Media’s In Proximity podcast, Coogler and Michael B. Jordan explored the complex history that shapes the film’s characters from the very start.
Coogler described the brothers’ turbulent upbringing in a violent household, which reached a turning point when Smoke killed their father to protect Stack. This defining event set their paths apart, with Smoke becoming the guardian and Stack the idealist. Their World War I service further impacted their lives, particularly Smoke, whose combat experiences left lasting physical and emotional effects, such as his constant alertness and difficulty relaxing.
Life After War and Fractured Family Ties in Mississippi
Following the war, the twins returned briefly to Mississippi, where tension arose as Stack developed a romantic relationship with Mary, a character who was once considered more like a sister. Smoke strongly opposed this relationship, resulting in a period during which the brothers were estranged. The separation ended with a heartbreaking tragedy involving Smoke and Annie’s daughter, marking a low point that ultimately brought the brothers back together in Chicago.
Formative Years Amid Chicago’s Harsh Reality
Chicago proved to be a harsh but pivotal setting for Smoke and Stack. According to Coogler, their work there involved untraceable tasks linked to organized crime. These experiences taught them about violence, power, and survival, laying the foundation for their characters as audiences meet them in Sinners.
Michael B. Jordan’s Approach to Bringing the Twins to Life
Jordan revealed his method for differentiating between Smoke and Stack during filming, which included maintaining separate journals and crafting distinct vocal tones for each twin. He also used physical and energetic techniques inspired by chakra work to embody each character fully and transition smoothly between them on set.
