Short of Dukhan take a right turn at intersection on dukhan highway and you will be heading towards zikreet.Once you reach the village go west towrds the shore and you will find a track along the beach heading North.Your sedan can go until here but to go to the film city you will need a GPS and definately a 4WD since the track gets a bit rocky and uneven as you move east away from the beach and towards the Film City.
