Debutant Vishal Jethwa, who plays a brutal serial rapist in the latest release Mardaani 2, says prepping for this film was a painful process for him emotionally.

"I'm a very happy, social person so this character is a complete contrast to who I'm in real life. It was very, very hard for me to become Sunny but I knew I had to prove myself as an actor. The preparation for this film was a painful process for me emotionally," Vishal said. The actor says he prepared really hard for the dark character named Sunny in the film.
