Argo
Taking place in Tehran, Iran, the entire film of Argo was actually shot between LA and Istanbul in Turkey. At the time of filming, there was no way for a US film team to enter an active warzone in Iran. Though they wanted to shoot for a couple of weeks, they wouldn't leave untouched, so they chose instead to film in locations like the Grand Bazaar and the Hagia Sophia Mosque in Istanbul instead of some of the ornate buildings recognizable in Tehran, Iran. These places are just normal tourist hot spots you can visit next time you go over there.
