The whole point of that article I linked
is that things like hardline Islamism
can't be combated through the use of movies. From that same article:
> Pakistan’s ideology is based on Islamic ‘nationalism’ where it views itself as part of a greater ‘Ummah’, but is certainly not recognized by the members of the ‘Ummah’ as its leader. In other words, Pakistan does not have native ownership over its own ideology, which inevitably leads to Pakistan associating itself with other, more influential members of the ‘Ummah’ like Saudi Arabia and Iran, at the obvious expense of its own subcontinental origins.
Neither Pakistan nor India wield a significant influence in the Islamic world - that power belongs to the aforementioned Saudi Arabia and Iran. No matter what may or may not happen in Bollywood, its influence in Pakistan/Afghanistan/etc. will always be overshadowed by Saudi & Persian mullahs. The reason why mullahs from those countries have the sort of transnational power they do is because of the unifying nature of Islam, across ethnic, cultural, and linguistic boundaries.
But the further west you go from India, the more the "influence" of Bollywood declines (and it is quite rapid). Regardless of whether the top Bollywood actors are Muslim, India itself is almost 80% Hindu, and that will never be forgotten by those in the Middle East watching Bollywood movies.
Although to those of us in the West, it may be easy to lump India and the Middle East into the same "cultural" category, that couldn't be further from the truth. Shared "conservative" values only go so far, and their respective histories are quite different.
