Iran's film censors have their work cut out for them:

There are 37 rules, laid out in 1983, 1993, and 1996 laws, detailing the ideas and images banned from movies. Many pertain to women: no close-ups of their faces, no makeup, no exposed necklines; men and women can't sit closely, appear to be alone together, touch, or exchange "tender words or jokes." Veiled women, bearded men, policemen, and soldiers can't be portrayed negatively without "a good excuse." No booze, no profanity against religion (yes, Iran protects faiths other than Islam), or neck ties, which are seen as a symbol of foreign culture. Oh, and no sorcery — sorry, Harry Potter.

Iranian journalist Reza Valizadeh explained in a 2010 interview "that beer becomes lemonade on state television and whiskey becomes orange juice."
