The Oscar isn’t the only one celebrating its 93rd trip around the sun at the Academy Awards ceremony this year. The shorts category features two documentaries, “A Concerto is a Conversation” and “Colette,” about nonagenarians who have led extraordinary and extraordinarily different lives. Horace Bowers is a 93-year-old Black man born in the Jim Crow South who went on to be a successful business owner in California and the grandfather of a prominent composer. Colette Marin-Catherine is a French woman who was part of the resistance during World War II. Neither dreamed that they would have any connection to the movies at all, let alone Hollywood’s greatest honor.
