Eva Green and Louis Garrel are electric as Isabelle and Theo — raw, unpredictable, and ferociously alive. Green’s Isabelle is a volatile mix of vulnerability and command; Garrel’s Theo is aristocratic mischief with a streak of menace. Michael Pitt’s Matthew supplies the film’s moral fulcrum: uncertain, eager to belong, and increasingly unmoored. Their chemistry drives the film, making its excesses feel propelled by genuine emotional volatility rather than mere provocation.
