Great actors have no parallels. They leave such a strong impression that whoever does it again fails to achieve the same amount of fame.
When we look at the last two examples in Kannada Swathi Muthyam of Kamal Hassan was remade as 'Swathi Muthu' starring Sudeep and Meena. This did not bring the investment back to producer Sarovar Sanjeev father of actor Sudeep.
The second example is 'Love Story' starring Mayoor Patel and Tanu Roy a remake of 'Maro Charitram and Ek Duje Ke Liye'. This is a miserable failure and the whole film was like a company drama. For producer Madan Patel it was a disaster once again as a producer.
Probably because of sensing these dangers Ramesh Aravind cleverly brought back Kamal Hassan to 'Rama Shama Bhama' a remake of 'Sathi Leelavathy'.
That is why we say Kamal Hassan Ka Jawab Nahin!
