The Oscar-winning actor says she decides to pick a role if it stays with her even after finishing the script reading session, reported The Sunday Times' Style magazine.
"I feel very privileged. It (fame) has given me the luxury of choice; I get to choose and work on things I can't stop thinking about. That is how I choose a project - if I read the script and after I leave it, the character lingers in my head. If I am not terrified of the character, then it is probably not for me," Nyong'o says.
"I am more familiar with (this world). I have my likes and dislikes. I know when I am spreading myself too thin. Now I know how many hours I need to sleep.
