Sexy Heroine freaked by porn film

Professional artists always do home work for any special characters come their way. Sultry sex siren Vidya Balan is usually regarded as more than professional for her dare bare acts with heroes. The hot lip-locks and raunchy scenes is a regular cup of tea for her. New one to join her list is ‘The Dirty Picture', biopic on south porn star Silk Smitha. Given the demure actor's new racy act as Silk; media asked on has she done any research and ground work watching any porn films as preparation for the role? Vidya answered, "No, not at all because I feel porn is more of a guy thing. A friend of mine recently gave me a film called Caligula and I was completely traumatized by its explicit content. It is not really porn but still it freaked me out." Watching Caligula as an inspiration for 'The Dirty Picture' is not sounding right Vidya.
