"I am a very calculative producer. I make films like business. Yes, I am passionate about films but along with passion I am very calculative. When you put your hard earned money, you have to be calculative," Kumar told IANS.
The "Baby" producer is currently busy promoting his next film "Roy", helmed by new director Vikramjit Singh.
"When I met him for the first time, he was a newcomer. I didn't find him convincing, but the story was very different. The story was very convincing and Ranbir (Kapoor) also told me that I do all kinds of films and this film is an unusual one," Kumar said.
Starring Ranbir, Arjun Rampal and Jacqueline Fernandez, "Roy" will release Feb 13.
