Dhanush, Siva Karthikeyan to clash: What’s brewing?

At a time when Siva Karthikeyan and Dhanush are making news for reasons that would have been considered improbable years ago, it's instructive that they are going to promote their respective movies at the same time and at the same venue, tomorrow in Hyderabad.  While Siva Karthikeyan will hold a 'Remo' event, Dhanush will participate in the audio release function of 'Dharma Yogi' ('Kodi').  

This makes one wonder as to what might be brewing.  

'Remo', produced in Telugu by Dil Raju, has already got its share of publicity for obvious reasons.  On the other hand, Dhanush hasn't had an exciting time after 'Raghuvaran B.Tech'.  'Anekudu' and the recent 'Rail' ('Thodari' in Tamil) didn't bode good news.  In this context, professional rivalry between the two actors has been alleged and profusely gossiped about in media circles, not to forget on social media.
