Yes, Kamal Hassan can do many things at the same time.
He is one of the hardest working heroes of Indian cinema. Though he was not successful in Hindi, in Tamil, he is still the Superstar, and is streets ahead of the other guy, Rajnikant, in terms of acting.
For instance, his film Nayagan, was an all time classic. His acting was simply superb. Ditto for Vishwaroopam, where he acted so well. This film was all about terrorism.
Now, his entry into politics. It is quite refreshing to note, that till date, he has not made a single paise of black money. He has paid all his taxes, and all his salaries are in white. He is on record as saying that he hates black money. Even today, his fans contribute to his political expenses.
He merely talks. He has already done some solid social work, particularly connected to water management and rain water harvesting. The public have started to believe him.
He is a die hard atheist. However, he is shrewd to jump to the Dravidian platform, and is sure to win so many friends. His tie up with the DMK is almost sure. He is way ahead of Rajnikant, who has just started speaking now, on various issues.
Rajnikant's record in social work, is a big zero. With a net work of an estimated seventy thousand crores, this guy is one of the richest Indians. Yet, he did not give anything more than a mere ten lakhs during the 2015 Chennai floods. He is yet to make a single sensible political statement. He is widely seen as a benami of the BJP and this is a huge minus. Kamal Hassan does not carry that baggage at all.
Yes, the Big Boss is likely to win at least a few seats in the Tamil Nadu assembly and dominate the TV screen with his very famous TV show.
