Toilet "ek prem katha" is a film based on a story of man and women who married with each other and after marriage the bride come to know that her husbands house has no toilet and she go back to her mothers house. Its a very basic story line that everyone know what will be happen in the end. I didnt watch the movie but after watching the trailer I can understand the whole story.
It is also relates with the Pradhan Mantri Swach Bharat Abhiyan and Akshay personally went to PMO to meet the prime minister to tell him the film story. So may be it has possibility that it can be a tax free movie. I think film can do a business of approximate 50 to 60 crore because it relates to PM. Although who will go to watch Akshay Kumar boring comedy.
