Stewart revealed what it was like growing up with six siblings in Nutley, New Jersey. She said her drive for perfectionism came from her father, Edward Kostyra.
“Dad made each of us learn how to garden. He could grow anything,” Stewart says in the documentary. “I was the ideal daughter. I wanted to learn, he had a lot to teach, and I listened.”
“It was very obvious to everybody that I was his favorite,” she added. “He thought I was more like him than the other children.”
But Stewart said her father was also a “dissatisfied, unhappy human being” who would sometimes begin the day with a glass of red wine alongside his coffee. Frank Kostyra, one of Stewart’s brothers, said their father would whip his children with a yardstick or the end of a belt.
Stewart said her father also hit her when she told him that she was engaged to Andrew Stewart.
“I went home and told my dad, and my dad slapped me,” she recalled. “He slapped me hard on my face and said, ‘No, you’re not marrying him. He’s a Jew.'”
“I remember getting that slap,” Stewart added. “I was not at all surprised because he was a bigot and he was impulsive. But I said, ‘I’m going to get married no matter what you think.'”
