Varun Dhawan is the original VD. Everyone in Dharma Productions, the banner with which he made his debut refers to him by his initials. However, Tabu calls her Drishyam co-star, Ajay Devgn ‘VD’. Back in the day, before he made his film debut that is, Ajay was called by his real name, Vishal Devgn. And Tabu, her first cousin cinematographer Sameer Arya and others in the Juhu neighourhood called Ajay ‘VD’, short for Vishal Devgn.
God, how much confusion all this name changing and name calling involves!
