As of July 2007, "Shivaji" is highest grossing Tamil movie ever. It grossed 100 crores (1 billion) Indian rupees in it's third weekend. First Tamil film and non-Hindi Indian movie to gross 100 crores and also the fastest Indian movie to gross that much.
Rajinikanth 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 woman's skin and grafts it into the superstar's 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 Indian cinema, if not in World 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.'.
In the film, "Boss" stands for "Bachelor of Social Service."
Sivaji is the first ever Tamil Movie to appear in the U.K Top Ten. It was released in just 12 screens all over U.K and gained the nineth place.
