Shankar’s upcoming biggie with Vikram in the lead finally got into action yesterday. Titled 'I', the film hit the floors in a studio in Chennai.

'I' is a romantic thriller and reportedly, Vikram is really happy with the script.  "The script work is over and writers Suba have done a great job. Shankar is happy with the writer duo since he was on the lookout for a right replacement after the demise of Sujatha," say sources.

Leading lady of the film Amy Jackson, plays an international model. Music of the film is by A.R Rahman and international technicians have been roped in to give their expertise.
