If you decide to revisit a beloved film from 1939, some of its most appealing qualities are bound to be altered to suit contemporary tastes. Herbert Ross and Leslie Bricusse attempted this with the story, and generally it's acceptable. Peter O’Toole portrays the meticulous Latin instructor at the boys’ school “Brookfield,” where he isn't particularly well-regarded by his colleagues or students. During a trip to London for a show, he encounters the performer "Katherine" (Petula Clark), though their initial interaction is awkward. A subsequent encounter in Pompeii sparks something between them. Their return to the school exposes both of them to evolving viewpoints concerning him and her, which challenges their developing relationship and his dedication to a career he’s long prioritized. With World War II approaching, the school must also adapt its values, leading to the dismantling of the established class structure and marking the end of an era—an ending brought about by a wartime loss that leaves “Chips” feeling lost in a new world. The production is polished with careful attention to detail, but it misses the romantic feel of the Robert Donat and Greer Garson version, especially regarding the Blue Danube waltz. The character of "Katherine" here is more assertive and self-sufficient, which probably aligns better with the late 1960s, however, this modernization made the film feel somewhat ordinary. I also felt it was missing a truly memorable song; neither “Fill the World with Love” nor “You and I” linger in memory after repeated appearances. Perhaps I’m simply drawn to the original's emotional core, but while I found this version enjoyable, it doesn’t elicit the same emotional response or capture that sense of fading grandeur and importance as the earlier film did. Nevertheless, there is a genuine connection between O’Toole and Clark—she certainly knows how to sustain a note—and it’s an adequate adaptation that's difficult not to appreciate.
