Santhanam is among the busiest stars in tinsel town and producers would go to any extent to have him in their movies. Such is the pull that he has on the audiences. He is a part of so many projects that sometimes, his schedules get mixed up.
Recently, Shankar had planned to shoot some scenes with Santhanam on a particular day's schedule of I. But, Santhanam could not make it to the shoots of I as he was occupied with some other movie. He revealed the same to Shankar who understood his plight and decided to cancel that day's shoot.
