New Delhi, Aug 2 (ANI): Sidharth Malhotra and Katrina Kaif are sharing the screen space for the first time in a high concept romantic film Baar Baar Dekho. While the song ‘Kala Chashma’ and the sizzling stills from the film are making people guess the off-screen chemistry of the duo, during the Baar Baar Dekho round table conversation with Karan Johar, Sidharth revealed he wasn’t comfortable with Katrina initially. When Katrina was speaking about her first experience of undergoing workshops, Sidharth admitted that he was blown away with Katrina’s blow hard, blow cold chemistry with him but later on agreed that it takes time for people to get comfortable with each other. However, Katrina in her defense said she was just doing what the scene required. ‘Baar Baar Dekho’, produced by Dharma Productions and Excel Entertainment, is a film by debutant director Nitya Mehra. The film is scheduled to hit the screen by September 9.
