About Rajini, hero of the film:
He is well known actor worldwide. People call him "Super Star" because of his unique style. He is the 2nd highest paid actor in Asia after Jackie chan. In this film, director Shanker wanted to change Rajini's wheatish complexion to a white European complexion. As a visual effects company (Indian Artists ) this was a challenging task for us because we guess nobody has executed this type of concept in the world. Thanks to Mr. Shanker for giving us this opportunity to execute his brilliant idea.

The Technique behind Dark skin to fair skin:

To begin with, we (Indian Artists) did an in-depth study of the European complexion.  We found that white skin reflects more light and has less shadow when compared to dark skin and is translucent in some areas. Therefore a simple color correction of the hero's skin would not achieve the desired effect.
