Do you think Indian Cinema Industry really lives off the profit it makes from Pakistan ? It has survived for decades based on profits it makes from India only. Now we have a global reach and that is only increasing. Indian movies get premiered all over the World, China, Japan, UK, US, African countries etc. There is a certain degree of advantage in case of Pakistan, which the language. But then, dubbing is also done. So, I don't think you are going to make an impact with that.
Also, there are a certain section of people in Pakistan who make a lot of profit by showing Indian movies and those are also the people who are usually in position of power, not people like you. They will not like it is their profits go down.
Did you get any chance to look at the American movies and TV series lately ? Hahaha You should....
