They might have their own space in the market but still it’s a rivalry at the box office as Siddharth and Ravi Teja test fortunes with their new films. Siddharth’s romantic entertainer ‘Love Failure’ and Ravi Teja’s mass masala flick ‘Nippu’ are releasing on February 17. With both the actors desperate for success, Tollywood box office fight gets interesting ahead of the Sivarathri festival. But what’s common between ‘Love Failure’ and ‘Nippu’ is that Thaman has rendered music for both these big ticket films, for which the music has already received good appreciation. Interestingly, Siddharth replaced Ravi Teja for his upcoming movie besides Samantha to be directed by Nandini Reddy.
