How did he perform? Did he surprise you at any time?
No, he is not a spontaneous actor. He practices each scene several times, keeping in mind exactly what I want.
For some complicated scenes, I would send him the script up to two days in advance. But he was never tired of practising and experimenting. For certain scenes he grew a tummy, and in other scenes, he has a very macho look.
Nowhere in the movie will you see Vikram. He was the character personified.
