This refers to the news item, "Nanak Shah Fakir: Dilemma and the Solution" (April 15, 2015 - The Tribune). All religious communities define sacred and profane in their ways and institute taboos to separate the two domains. For instance, no one is allowed inside a gurdwara with an uncovered head, but there is no such restriction on Christians entering a church.
Often such practices are connected with a deep logic rooted in a community's specific history, culture and worldview, which is not always clearly understood even by followers. In line with this argument, there should be no objection if Sikhs disapprove of showing their Gurus live in film.
To be sure, feature films is not the only way to instruct the world in Sikhism, nor are Sikhs obliged to imitate others who choose to rely on this medium.
Educational films consistent with Sikh sensitivities can indeed be made to present Sikhism in its full glory and authenticity for viewing by all.
The SGPC will do well to form a panel of experts, get all the issues thrashed and work out an unambiguous policy in regard to the portrayal of Sikh Gurus in films.
