Kareena Kapoor has attacked critics who say that her performance contributes little to the success of the films she works on.

In spite of acting in Bodyguard and Ra.One - two of the biggest hits of 2011 - the actress has been criticised for choosing to act solely in commercial cinema.

"If I wasn't doing these big films, then what am I supposed to do?" Kapoor questioned Bollywood Reporter Sunny Malik.

"Angelina Jolie also acts in the biggest films in Hollywood because she is the biggest star. If you are offered a film like Ra.One, Agent Vinod, Bodyguard or Talaash it's obvious that some people feel, 'Why has it all gone to her?'"

Kapoor said that many of her earlier film projects involved collaborating with first-time filmmakers and in more experimental roles.

"My route to success started way back with Jab We Met. I mean Imtiaz (Ali) was a new director. I took up a film that nobody would have done, or Chameli for that matter," she explained.

"I don't think anyone would take up a film like that so early in their career. Now, I am just enjoying where I am."

She went on to add: "Obviously it's people who are feeling that there is too much happening but I think it's okay. There has to be a downside to the success."

Kapoor will be seen next in Ek Main aur Ekk Tu, which releases February 10.
