The remarkable thing about this movie is that it was fully conceived, filmed, and released *before* Anwar Sadat and the Camp David Accords, and, in its own way, echoes the events in its own future. If you are too young to remember these events, then I recommend you look it up in Wikipedia... Then realize that this movie did not follow that history, it preceded it.
Not much should be expected of the movie, it is a definite B-movie from Connery's lower-rent period, when he did a lot of doubtful pictures following his "Never Again" appearance in "Diamonds Are Forever", and before his talent, so evident in his early, pre-Bond pictures, was re-recognized by critics and fans alike.
It is a decent and effective, if not surprising picture, and Connery himself does an effective job as an Arab leader seeking to end the strife with Israel, against substantial political opposition. At the time, the whole idea of it seemed preposterously far in the future, but in reality, the Camp David Accords were less than 4 years away.
