A girl is looking for her father who disappeared somewhere in mid-Asia (I think). The girl meets and hires a pilot, a cynical drunkard - their hate and love relationship is the major part of the story, their conversation is full of humor. There is a link to British government or secret service (the father was representing these, or was perhaps a scientist?), this part is humorous, too. There are local bad guys and tribes, a lot of fighting with air-raid against the locals (action film part?).
Not a good film, not a famous one, probably no reason to remember it. We saw it some 10-15 years ago, and a few lines of the dialogue keep coming back continually, like the pilot shouting 'don't speak!' to the girl, and a little later, becoming interested, shouts with the same tone 'speak!'.
If any of you can identify this film?
