Factual error: The tiny missiles on the F16 are shown as being attached to some sort of flexible metal framework which bends and shifts as the plane moves along the ground. The F16 is a supersonic fighter - any such thing would be ripped clean off the wing at speed. The missiles carried by the F16 are attached to streamlined 'hard points' under the wing, or the wingtips themselves.
Continuity mistake: When Joan meets The Jewel for the first time in the room where Omar is holding him prisoner, Omar enters and greets Joan. As he leaves, the shot shows Joan with her back turned to Omar and Omar is heard off-camera saying Joan looks pale. How does Omar know how Joan looks if he doesn't see her, and there is no mirror on the side of the room where they are chatting? (00:36:35)
Joan Wilder: My heart just isn't in it. I mean, romance just doesn't seem real to me anymore.
Gloria: Real? You don't write real - you write about people that sail off into the god damn sunset.
Joan Wilder: Well, what about the next day, when the sun comes up?
Gloria: There is no next day! That's why it's a romance. You've got to stop confusing real life with a romantic novel.
Question: Does anyone know where the idea for the Arab flag in the movie came from? Seems to me it resembles the Louisiana flag (the bird with the babies) except with no writing. Did anyone else notice this?
