You couldn’t ask for more dramatic and entertaining material. Landsman edits between period clips of benevolently demanding father-figure Prof and the band in its prime—unexpectedly beating all the white bands in competition—and contemporary footage of the 90ish prof, who was kicked to the curb by misguided school officials, and the grateful 50ish students whose lives he changed… I wouldn’t be surprised if this movie wound up in the Oscar race. It has the right elements to appeal to warm-hearted Academy voters.
