My wife and I watched this movie at home on DVD from our public library.
In 1981 was a movie "Chariots of Fire". The IMDb synopsis is "Two British track athletes, one a determined Jew, and the other a devout Christian, compete in the 1924 Olympics." That Christian athlete was Eric Liddell (lid-uhl) who set a record but refused to compete in trials scheduled on a Sunday.
This movie "Wings" is a continuation of that story some years later as Liddell has returned to China, where he was born to British missionaries, to teach. Joseph Fiennes plays the role of Eric Liddell and most of the movie is during WW2 when the Japanese have imprisoned many of them.
It is a good study of who Liddell was and how he likely sacrificed himself to provide freedom for others. Not a pleasant movie but a meaningful one.
