Sandra Bullock has revealed that she doesn't accept any acting roles unless they provide "great life experience" for her son Louis.
Bullock won an Oscar for her portrayal of Leigh Anne Tuohy in 2009's 'The Blind Side', and her role in new 9/11 drama 'Extremely Loud & Incredibly Close' is her first since then. She adopted Louis in early 2010.
Speaking to ITV's Daybreak, she said: "The wonderful thing about the work that I do is that I don't do anything anymore unless it's the ideal situation for the both of us. If it's a great life experience and my son can be there while he's mobile – before school starts – to have the greatest time, then I can do it.
"And they made ['Extremely Loud...'] so heavenly - everything was about Louis. Everything was bumper-guarded and every corner was rounded."
In the new film, released on February 17, Bullock plays a parent whose husband is killed in the September 11 terrorist attacks on New York City.
She said: "The responsibility is to those who perished, those who were left behind, those who are experiencing the grief still. I mean there are so many facets to it, so every day we would come to the set and you did – you came to set with a great deal of responsibility in the palms of your hand."
Louis was recently photographed trying to make a run for it after school.
