Million Dollar Murder (2005)

Wall Street golden boy Ted Ammon falls madly in love with sassy saleswoman Generosa Rand, marries her, and wants to start a family. Unable to conceive, the couple try other methods; when they prove unsuccessful, they adopt twins, a boy and a girl. When Ted realizes that Generosa has a mental illness, he wants her to seek help, but she refuses, thinking he's saying she is crazy like her mother. During a bitter divorce procedure, she spends millions just to spite him, no matter how willingly he swallows the absurd terms; tries to turn both kids against Ted; and cheats on him with Danny Pelosi, a dodgy contractor with a criminal record. After Ted dies in suspicious circumstances, Generosa turns against Danny just as meanly, in favor of an English nanny/nurse once she is diagnosed with terminal cancer.
