Tanishaa Mukerji made her acting debut in 2003 with the multi-starrer 'Sssshhh...' She then played a lead role for the first time in the film 'Neal N Nikki' in 2005 opposite Uday Chopra. Despite the film being backed by Yash Raj Films, the film failed to perform and subsequently did not help in pushing her career forward. Tanishaa, who is the younger sister of actor Kajol, recently opened up about how her sister did not watch the film as it had 'many kissing scenes'. 

While talking to Siddharth Kannan, Tanishaa Mukerji said that Kajol has to date not watched 'Neal N Nikki'. "It was too much kissing on-screen. My sister (Kajol) has not watched the film till today. Even I tell my friend’s kids to watch it after growing up a little bit. That conservativeness exists in our country.”
