"I had the script of the movie for 12 years. It's a very special film for me. For me, Sunny is the only Leela and was the only choice for this film. She has done a fabulous job in the film," Khan, the director, said.
He says Sunny, who was a popular Indo-Canadian adult film star before paving her way into Bollywood, will be seen "like never before" on screen.
"She has completely transformed herself for this film and has worked really hard to justify her character."
