Filmmaking In Islam
Quran asks to dress in a decent way to cover Satr: The private body parts. Head is not supposed to be a private body part. So Islam does not ask to cover it. This is the culture that tells what is considered decent in dressing. The interaction of men and women, dressing, and the content of the movie, etc are matters of morality and ethics. Our sense f morality and ethics helps us decide in such matters.
Hijab is not any injunction in Islam. There are only manners to dress up for women when they have adorned themselves with make up and jewellery etc. This extra beautification is asked to cover in front of men. If no extra beautification is done, they are asked only to dress decently, the same is for men see verse 24: 30-31. The Hijab injunction was only for the wives of the prophet in face of some special conditions mentioned in Sura 33. and its verse 32-33 and 59. The verse 50 tells an administrative measure to snub the mischief makers and to cut their excuse to punish them later. This too is not a general injunction.
