'Kaala' is dark. It has crime, corruption power play, and revenge. When Taher was asked if he feels the burden if he is assigned such a role that is so intense, he said, ''If you don't prepare for the character, then it becomes a burden. If you are preparing for any character, it's the same. In my case, when I play a character which I don't relate to because I don't relate to Naman at all obviously. So, it's not harder but it takes time. When you are preparing for the guy and when you start to fight a case of his justification, if you do that well then it becomes easy and it's not a real burden. Yes, it is a little bit hard not in terms of an actor but as a person to start to believe that whatever the person is doing is right. So, obviously, when you are playing an antagonist, it is a bit difficult but the burden you are talking about is the same in any character you play because ultimately you have to prep. If you prep well, it is really easy.''
