 Rajnikanth (qv) appears as a white skinned European guy in a song  sequence. The Digital skin grafting effects used to create the dark  skinned Rajini into a white skin guy took almost one year with the  help of 25 technicians. All this, with the help of computer graphics  that lifts a European womans skin and grafts it into the  superstars face. Each of the over 6,500 frames had to be worked on  individually and he same process has been used to create an almost  black Rajini in the song sequence too. This process is said to be  the first in world cinema, if not in Indian cinema. "Whatever shot  we took with Rajini sir, we took with a white girl we selected. We  went for the girl because she would have softer skin and flushed  cheeks. We took the tone and texture from her face and applied it on  his face," said cinematographer Anand K. V. (qv).
