45. Brother Against Brother (and Wife)
Movie: Raging Bull (1980)
Director: Martin Scorsese
Stars: Rober De Niro, Joe Pesci, Cathy Moriarty
Fighting between brothers is a common and expected occurrence, though De Niro and Pesci, as Jake and Joey LaMotta, took the sibling squabbles to a whole new level. In a fit of jealous rage, the titular boxer barges into Joey's home, lands a few punches on him, throws him through a glass door, and starts stomping the man into a bloody pulp over the assumption that Joey had an affair with his wife.
In an attempt to calm her husband down, Vickie, played by Cathy Moriarty, finds herself knocked out by one of the fighters's blows. The emotional violence coupled with the physical domestic violence makes for a potent combination. You want to look away because it feels too real, like hearing the neighbors go at it. —TA
