Some of Bollywood's biggest stars are joining the efforts of the United Nations Office on Drugs and Crime (UNODC ) to curb human trafficking in India.

Millions of moviegoers in India will see a two-minute video called One Life, No Price - aiming to raise awareness of this form of modern-day slavery and spur action to prevent and combat this practice - to be shown before the eagerly awaited comedy, Welcome, out in cinemas worldwide starting today.

The video features the massive cast of Welcome, including Feroz Khan, Anil Kapoor, Nana Patekar, Akshay Kumar, Katrina Kaif, Paresh Rawal and Mallika Sherawat, who have also recorded separate messages in support of the cause.

Given that Welcome is the biggest release of the festive season with a diverse star cast, popular genre and universal appeal, it was seen as the most appropriate vehicle to publicise this priceless cause and mobilize action.
