He has written in his blog that he has decided to call off due to some personal reasons.
Though no particular reason has been cited, Vishal has written that it was a tough decision to make and has justified it by saying "I always believe in the films I take up right from day one and till the very end. I also put all my efforts into them irrespective of what the result would be at the end of it. Some kind of positive force would keep me going...but this time I have felt otherwise ...wouldn't want to tell anything more. I hope to work with Selva sometime in the near future. I respect him as a director and I wish him all the best in his forthcoming movie'.
Speculations are rife that the duration of the project might have been a concern for Vishal as Selvaraghavan is known for taking at least a year to complete a film.
