Chiyaan Vikram's three different avatars in Shankar's I, featuring Amy Jackson and Upen Patel, have become a talking point among his fans. The actor will be seen as a bodybuilder, a lean model and a hunchback in the film, which is presented by V Ravichandran and has photography by P C Sreeram.

Of course, adopting these distinct looks was not an easy task. Apparently, Vikram had to follow a rigorous workout regimen in a bid to lose 25 kilos to play the role of the model. He even revealed that it took him three years to achieve the lean frame and toned abs. His other look is that of a beefed-up bodybuilder who is vying for the title of Mr Tamil Nadu. His character is shown to be inspired by Hollywood star Arnold Schwarzenegger.

The actor's hunchback avatar has got a lot of attention. Not many know that it used to take Vikram almost five hours to get into this look

I, produced by Aascar Films Pvt Ltd, releases tomorrow.
