If there is one girl who is on a signing spree by dozens, it is Kangana Ranaut. Don't be surprised by the volume of releases that she had in 2010. She may have had four films of hers arrive in the year gone by but the volume isn't going to decrease over next two years at the least. Her only calling card in 2010 was Once Upon A Time In Mumbai, which was a clean hit, though she was criticised massively in both No Problem as well as Knock Out. Still, Kangana could well have people sing a different tone once she brings out some new goodies out of her bag in 2011.
