The idea of having a workshop before starting the actual shoot is in vogue now among so-called directors of substance.

Earlier directors like Suseenthiran, Kamal Hassan and others have followed this pattern and now Vetrimaran of Aadukalam fame was supposed to have a workshop for his upcoming film Vada Chennai.

But looks like his two-day workshop planned with actor Silambarasan and the team of Vada Chennai has been postponed.

Those slated to participate including STR,Rana Daggubatti, Andrea and GV Prakash were too busy to dole out dates, we hear.
