Can Rani & Saif work their charm anew?

After a short and pleasant break, Rani Mukherjee is back to another shooting spell. Knowing how much she dotes on her newborn niece, we're sure she wishes her break was longer. But well, working with the Yash Raj camp is like going back to family ground for her.Yeah, she and Saif kick-started the shooting of their second film together that's being directed by Siddharth Anand who shot to fame after Salaam Namaste. It’s deja-vu time for Rani and Saif because they'll be rekindling their chemistry after the super-successful Hum Tum.Saif and Siddharth will be bonding again after their last success Salaam Namaste, and to top it all, Kunal Kohli's (director of Hum Tum) wife, Raveena, is the executive producer on this project.So it's like an 'everyone-knows-someone' kind of setting. But there's a lot more we film buffs would like to know. Over to Rani and Saif.
