In the past, Kapoor cousins Ranbir and Kareena have shied away from playing lovers in a Bollywood project. But award-winning director Zoya Akhtar has come up with a perfect solution. If they can\'t make play lovers, they sure can play siblings. According to the grapevine, the Zindagi Na Milegi filmmaker narrated her story idea to the actors on separate occasions and both grabbed at the offer. Though Bollywood musicals hinge on sweeping romances, this one is likely to focus on the bro-sis dynamic and their turbulent relationship. Meanwhile, Ranbir seems to be on a signing spree and is all set to play a bloodthirsty vampire in Bloody Veer.
