She has already made her big Bollywood debut with Jism 2 earlier this year. Now Sunny Leone will have to go through an extensive preparation programme for her second film, Ragini MMS 2. Starting December end, the adult film star will kick off a month-long prep course for Ekta Kapoor's horror film.

"Being a thriller-horror, it's going to be a very performance-driven role. And that's why Ekta and the creative heads at Balaji don't want to take any chances. So, four different trainers are in the process of being appointed to train Sunny in different performance forms.

While two of them will coach her in acting and diction, another one will be involved with physical training because a lot of cable work and harnesses will be used while filming. I cannot divulge details about the fourth coach," says an insider close to the project.

When contacted, Ekta says, "Yes, we are going to hire trainers because at Balaji we always strive for perfection." Ragini MMS 2 is the sequel to last year's sleeper hit. Sunny has already been through a detailed narrative of the film.

"She has been asked to watch a number of American horror films and TV shows to get into the groove because she is scared of horror movies. So, the Balaji creative heads have marked certain scenes and sequences from these films and shows for her to use as reference points," adds the insider.

Sunny, who is currently in the US, is flying down to Mumbai by mid-December. "From then on, her training process will also kick off. She will take a small break for New Year's and then her coaching will continue until the shoot starts on January 15," adds the insider.
