Actress Kareena Kapoor Khan has said that her character 'Poo' in 2001 film 'Kabhi Khushi Kabhie Gham...' was way ahead of its time. "It was such a bold character. I don't think any Indian actor could think of doing it...I think 'Poo' is a character that can't be replaced. It can't be done again on screen," the actress added.
