'Ishtar' sounds like it should be a tragic documentary about the middle east. Instead it's a tragically unfunny film about the middle east. As much as I love the adventure comedy genre, the movies actually have to be good too. Even in 1987, audiences weren't accepting of any old bull crap that the studios would put in front of them, even if that bull crap starred Dustin Hoffman and Warren Beatty.
This movie lost the studio eighty seven million dollars. That's the price you pay when you fly off to Morocco (or some place that looks like Morocco) to shoot your movie. Shooting on location is extremely expensive. I'm guess shooting in Morocco is more expensive than, let's say, New Orleans. At least Duston Hoffman and Warren Beatty were able to give audiences a crash course in Moroccan life (sort of).
