Director Vivek Agnihotri says it was filmaker Vikram Bhatt who inspired him to make Freedom.
Freedom is a socio-political saga set in the backdrop of 1970s to 2000s. It features Salman Yusuf Khan in the lead.
"I always wanted to make Freedom, but I had to drop the idea due to financial crisis. I would have never made an erotic thriller like Hate Story if I had finance for Freedom. Vikram gave me Hate Story as a challenge. Apart from Vikram, one of my friends also encouraged me to make a film on this subject," Agnihotri said.
"While thinking about Freedom, I took Hate Story as a challenge and did justice to it. We shot it like a beautiful international thriller. I am happy people loved the film and it also earned good money to start my ambitious project," he added.
Hate Story released in 2012.
