Karishma Kotak will act against Arjun Rampal in Pooja Bhatt's “Love Affair.” There were a lot of speculations over Karishma's role and also the storyline of the film. When asked, Karishma said the film was based on the Nanavati murder case of the 50s and 60s. The film is set in that era, so special preparations have gone in to get a feel and look of my character, that of a top actress from those times. I play Arjun Rampal's love interest in the film. There is also Kalki Koechlin and Diandra Soares. When asked about the music director, Karishma said she did not know anything about it since it was a film by Pooja Bhatt.
