Actress Karena Kapoor says in the past she has done a lot of films for the sake of friendship, but now only a film with a "good story" will lure her.

"I have done a lot of films for friends. Now I want to do films for story. I don't regret it (having done any films for friends) and for me, it's never a mistake. I am like that - I always think from the heart, so it's fine," Kareena said here.

The actress, who has been part of some commercial films like "Kabhi Khushi Kabhie Gham....", "3 Idiots", "Bodyguard" and "RA.One", has also done offbeat roles in films like "Chameli" and "Talaash".

What was her reason behind choosing those?

"I did 'Chameli' and 'Dev' becaue I needed to balance myself. I come from a family where I needed to prove myself. I was 21 when I played a prostitute in 'Chameli' and I played it again in 'Talaash'...both have been great films of my career," she added.

Now that Kareena will soon be seen in a commercial film like "Singham Returns", is she open to the idea of taking up an offbeat movie at this point of time in her career?
"I will do that but I won't do it just for the sake of it because I did 'Dev', 'Chameli' and 'Omkara' when I was the most (successful) commercial actress. At this stage, I will not do a film just like that or heck of it, because I have done that and I am happy doing commercial films."

"I don't have to prove anything (now). Most importantly, the script has to be good."
