Tarun Khanna came to be noticed after the controversial Pepsi ad and according to him this ad is lucky for him. Although the promotional ad for Phir Bhi Dil Hai Hindustani, one of the Pepsi-ad series was his first, it hardly got him noticed. When his other campaigns with Pringle, Four Square and Maruti also did not get him the needed recognition, the Pepsi ad with Shahrukh Khan did the trick. Tarun declares, "As far as this ad is concerned, it is probably a sheer coincidence that I look like Hrithik. Also there has been no attempt to prove that Shahrukh is better than Hrithik.
Tarun very much resembles Hrithik and according to him at times its quite annoying to be called a Hrithik look alike. Tarun has now focused his attention to showbiz and is making his debut appearance with a Mahesh Manjerekar film Tere Pyar Ki Kasam, which also stars Sunil Shetty, Mahima Chaudhary and Hrishita Bhatt.
