What's the connection between Soundarya, Pranav and Dhanush?

Mohanlal's son, Pranav Mohanlal, will soon be a part of Soundarya Rajinikanth- Dhanush's film Pranav has also signed Jeetu Joseph's action thriller for his debut

Pranav will be seen in an action avatar in the film. 

And the latest we hear is that Rajinikanth's daughter and son-in-law are planning to rope in Pranav for a mega budget movie in Tamil. Yes, you read it right. Pranav might actually make his Kollywood debut before he begins shooting for his Mollywood project. Soundarya Rajinikanth and Dhanush have combined for a project which will be penned by Dhanush himself. 

Though there has not been any official confirmation on the report, we hope that Pranav teams up with Dhanush and Soundarya.
