A Beautiful Mind
This 2001 drama isn't just about mathematician John Nash's descent into paranoid schizophrenia, it's about the unbelievable love story between him and his wife, Alicia. Russell Crowe and Jennifer Connelly played the couple, who were married for merely six years before divorcing. They remained close, resumed their relationship decades later, and eventually remarried. They died in a car crash together in 2015.
