I agree with Benjamin Stello of Sweden but want to add that the Film is made on Location in Beirut and is nearly Documentary. It is before Israel invaded Lebanon to get rid of PLO Terrorists. It shows the situation after Lebanese Civil War that started 1975. Beirut is divided into many Rival Quarters. The Palestinians Controlling part of Beirut. A Hellish situation where everybody is Against everybody. Similar to Yugoslavia some years later. Another Book I recommend is Thomas Friedman's "From Beirut to Jerusalem" which describes Beirut a few years later. This movie I only saw once in 1982 and is unforgettable. I also recommend other films by this Director. The Tin Drum and Others.
