Disclaimer - For me the Apple Support Communities are an international user to user technical support forum. As a man from Mexico my first language is Spanish. I do not speak English, however I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture very different from that found in most 1st world nations, such as that in the two dominant North American countries. Written language has no tone. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
Apple is in business to make money. So it is silly to think that Apple would not want to sell or rent movies to folks in Pakistan. The issue is that Apple does not own the content in the stores, Apple merely sells the content. Apple can only sell what it is licensed by the content owners to sell. Currently, the movie industry has not licensed Apple to sell movies in Pakistan. The people who you need to convince isn't Apple, but the movie industry. You need to convince the movie industry, the folks who actually own the movies, to allow Apple to rent and sell movies in the Pakistan iTunes Store. When you are successful with that goal, Apple will be happy to sell or rent to you all of the movies that you can afford.
