Top B-Town stars like Amitabh Bachchan, Nana Patekar, Akshay Kumar and Katrina Kaif (pictured below) have lent a helping hand to the United Nations and will be a part of the UN's effort to control human trafficking in India.

The actors will be seen in a video called "One Life, No Price" which is currently being played before the start of the latest release "Welcome." Other than the 'Welcome' gang, the video also has Preity Zinta and John Abraham speaking about the problem currently in India. Well it's nice to see that our B-Town boys and girls are using their power for all the right reasons!
