Shankar is one of the most successful directors in the industry. And it is said that the reason for his success is his hard work and systematic approach to filmmaking. It has been said that he is a perfectionist who can spend a lot of time on the most insignificant detail. Apparently, while shooting Endhiran, he waited for hours to get his hands on a pink towel. Later he told his assistants that compromising on even little things can ultimately derail a project and this was a lesson he had learned early in his career. It is typical of the man to take time out to explain things to his assistants instead of screaming at them for not having everything he wished ready.
