Stewart's age didn't bother me at all in this movie, although he was portraying a much younger person. I still recall my fascination with Lindbergh's story and while I was thoroughly adult by the time this biopic was made, I had to see it.
Not only does this boast a great performance by Stewart,it also gives a lot of fascinating technical data,making it understandable to those technically challenged such as myself. And the look of the plane itself was great.
I quite loved this depiction of a period before my birth and reawakens the childhood love I had for airplanes and for the idea of air travel.
