I can't say that this is the worst movie ever made but....
It is by far the worst aviation based movie ever made and has to be included in one of the say...30 worst movies ever made.
Or course a cast that includes Charo AND Jimmy Walker should be a major red flag.
And this movies contains one of the most absurd scenes I've ever witnessed, it is so bad that whenever I come across this movie and it's anywhere near the scene I have to wait until I see it; two bimbos "dancing" in the galley of the Concorde which can't be more than four feet wide, while Jimmy Walker plays the saxophone in accompaniment. You have to see it to appreciate the shear awfulness of it.
And there is of course the standard motely collection of passengers; someone transporting an organ for transplant, a deaf girl, an aging performer, on and on, the clichés are endless. A another great scene is when George Kennedy gets fixed up with a hooker without knowing it, really bonds with her, and sleeps with her, and when he finds out later she was on the clock thinks it's the funniest thing he's ever heard. He should have gotten an Oscar for best fake laugh in a movie that year.
Forget the complete foolishness of the flight scenes and the plot itself, some of the high points are priceless though;
The plane is going Mach 2 over the ocean and George Kennedy OPENS a cockpit window to fire a flare gun.
The two pilots fling the Concorde around the sky like a fighter plane without so much as popping a rivet.
The passengers, after suffering through two episodes of these acrobatics not only shake it off as if it were nothing but they get BACK on the damn plane the next day!
Crash landing the Concorde in the snow like a toboggan and it stays together!
Last but not least; just the awful acting throughout, has to be seen to be believed.
On the up side;
Susan Blakely who was still drop dead gorgeous when this movie was made. It she had a few scenes in a bikini I would have given the thing at least one star! And that's about it for the up side...
