The Fight Club star said that using a former porn star will help create a buzz around the project.
"Sunny Leone has given us publicity, which is more than what any actress would have given us," Morea told Digital Spy.
"We are happy with that, no questions asked," added the actor-turned-producer.
Morea also revealed that the Indo-Canadian actress would be allocated additional time to learn dialogue.
"We have sent her the lines already and she is rehearsing at the moment. She is coming about 15 days before we start filming and we will rehearse with the actors and her voice will mostly be dubbed," he revealed.
Director Mahesh Bhatt previously indicated that he chose Leone over established actresses such as Bipasha Basu and Katrina Kaif.
Leone will reportedly appear nude under sheets in the poster for the film.
