Vikram and Shankar have joined hands for "I" after the hit combo in Anniyan. Vikram is known for his dedication for acting. He has done a lot of getups before. He has gained and lost weight before. But for I vikram has put in a lot more dedication.
Vikram is doin a role of a 85 year old man in this movie. He has lost almost all his muscles for this role. He maintains a strict diet and exercise schedule. Shankar wants this role to be secret element as he maintains a secret element in all his movies. So shankar has strictly said vikram to stay at home and not to expose this getup to anyone. So vikram spends his time only in his home other than shooting spot and his personal gym.
