Why Sandra Bullock Kept Saying No To The Blind Side Before Signing On

Before agreeing to take on the role of real-life powerhouse Leigh Anne Tuohy, Bullock had some reservations. Her biggest fear was that she wouldn't be able to do Tuohy and her selfless actions justice on the big screen. Basically, she didn't want to mess it up. In an effort to ease herself into the role, Bullock regularly observed Tuohy, taking note of everything from her mannerisms to what energizes her to get out of bed each morning (via Tribute Movies). Also, not only did Bullock study Tuohy's personality traits, she created a lengthy list of her favorite makeup products, nail polish and clothes, right down to the underwear.

"It was really scary. That's why I just kept saying, 'No,'" reflected Bullock. "Leigh Anne will beat anyone in their energy, any day, in her sleep. When I first met her, I was thoroughly exhausted by the time I left her and she was still gonna go for another five hours."

Though Bullock entered "The Blind Side" set full of nerves, she's thankful that she went through with the role and feels she gave it her all.

"I left going, 'I have no idea what I did. I don't know if it's right. I don't know if I gave what I needed to give.' But I was spent by the time I left," she said. "It was a good life experience, not just for the work. I felt like I came out of it just bigger. You felt fuller when you left this place."
