Ranbir-Katrina's relation won't help selling a film

Bollywood producer Siddharth Roy Kapur says the off-screen chemistry between Ranbir Kapoor and Katrina Kaif will not help in garnering eyeballs for their upcoming film "Jagga Jasoos". Ranbir and Katrina, who are dating each other, have become one of the most loved jodis of the Hindi filmdom. When asked if the couple's relationship helps a film to do wonders at the box-office, Siddharth said, "I don't think so... The story helps sell a film better. It is Anurag (director Anurag Basu) and Ranbir coming together after "Barfi" so there is lot of excitement around the film and we too are excited about it." The two actors have worked together in "Ajab Prem Ki Ghazab Kahani" and "Rajneeti".
