Nayak said 'Bigg Boss Halla Bol', an extension of 'Bigg Boss 8', was planned right from the beginning as the reality series was doing good.
"These reports that 'Halla Bol' was introduced as 'Ashoka' was not ready are completely baseless. It was a pre-planned thing as the eighth season of the show was doing amazing.
"So, we thought that we should introduce a new segment with a new host and we have been getting good response," Nayak told reporters here.
The pre-production of the historical show took six months to complete including the building of the sets by 'Mary Kom' director Umang Kumar in collaboration with Nitin Desai.
"It was a challenge for me to prepare the sets for 'Ashoka' because it was not a mythological show where you can play with your imagination. But 'Ashoka' is a historical show and if we are not right with facts then we can land in a big soup," Umang, who has also created the sets of mythological show 'Mahadev', said.
Nigam said playing the greatest emperor of India was like revisiting his history lessons.
"I am in my 9th standard and my teacher teaches me history. I like Ashoka the most because I have learned about him on my own. I took three months time to prepare for my character," Nigam said.
Eminent actor Manoj Joshi is playing Chanakya. The actor has previously starred in Marathi TV series 'Chanakya', where he played Shriyak.
Asked if he was apprehensive about taking on the role, he said, "No, I don't have the fear of getting similar roles. If I get such great roles, I would love to do them again and again."
"We did an extensive research on the show and consulted the books available on him. We did dramatise some parts but it was done on dotted lines. The story starts from Magadh and Ashoka's journey from the woods to become the emperor," Abhimanyu Singh, CEO Contiloe, said.
