Commenting on the development, Mondelez International Associate Vice President -- Biscuits, India & South Asia -- Chella Pandyan said Ranbir and Karthi have universal appeal and personalities that perfectly fit the lighthearted personality of the brand.
"We believe that with both of them on board it is going to be a fun ride taking Oreo's appeal to the next level," he added.
The two brand ambassadors will be introduced through a delightful new campaign – 'Connect Playfully', based on the unique relationship shared by siblings, Pandyan said.
Apart from the TV commercial featuring the two actors, the company said it will also connect with the customers through a 360-degree campaign with outdoor, digital, radio and on-ground activities.
