The gist: Bette Davis plays heiress and playgirl Judith Traherne, who is diagnosed with a fatal brain tumor. She falls in love with her brain surgeon, played by George Brent. Geraldine Fitzgerald plays her best friend and secretary Ann, Humphrey Bogart plays her Irish horse trainer, and a very babyish Ronald Reagan plays her drinking buddy Alec.
On the surface, this movie is a melodramatic schlockfest in which Bette Davis reaches hysterical heights on a regular basis. It's considered a classic of its type.
Judith's horse Challenger is a central character in the movie, and a metaphor for Judith throughout. Trainer Michael (and oh, I could write an entire essay on Humphrey Bogart's terrible Irish accent) doesn't think the horse will ever amount to anything. Judith is convinced he's a champion. It's while taking him over fences at the beginning of the movie that she falls and is first diagnosed with her brain tumor. Michael brings Challenger to her bedroom while she's recovering, and his eventual admission that Challenger is a champion after all is another metaphor for Judith's acceptance of her diagnosis toward the end of the movie.
Incidentally, Bette Davis herself was something of a horse person, though perhaps not as deeply involved with the sport as her co-star in this film, Ronald Reagan, or other stars like Carole Lombard and Clark Gable. She renovated a home in New Hampshire named Butternut, and kept a horse there for her time off from moviemaking. I've also found mentions of horses she kept for her daughter as well.
Definitely recommended if you like classic film, and classic horse scenes.
