Angelina Jolie, who plays Mariane Pearl - widow of Wall Street Journal reporter Daniel Pearl - in 'A Mighty Heart', was terrified of portraying Mariane after meeting her.
Angelina said: "The day before we started shooting, I hardly slept and I was in a panic. I had gotten to know her, and I'd gotten to know their son. And the thought that he would see this one day.
"It was my responsibility to not just show the world but also show him how much his mother loved his father and how much they loved each other and how they handled this time. It haunted me."
