While Terence Winter’s screenplay heightened the drama for comedic momentum, the core beats of Robbie's scenes reflect genuine events from Jordan Belfort’s marriage to Nadine Caridi. A British-born model raised in Bay Ridge, Caridi met Belfort at an elite Hamptons pool party in the late 1980s while she was dating Alan Wilzig, the entrepreneur fictionalized as "Slosh" in the film.
Robbie met privately with Caridi before filming began to understand the domestic reality behind the tabloid chaos. Caridi explained that surviving Belfort’s cocaine binges required defensive fury, not passive victimhood. In real life, Belfort truly did kick Caridi down a flight of stairs and crash his Mercedes into their garage pillar with their daughter unbuckled in the front seat, a terrifying incident that finally forced Caridi to pack her bags and file for divorce in 1998.
Following the split, Caridi rebuilt her life completely away from Wall Street. She earned a Master’s degree and a Ph.D. in somatic psychology, establishing a private clinical practice as Dr. Nadine Macaluso specializing in helping women recover from narcissistic abuse and relational trauma.
