Once an American passion as the "sport of kings", horse racing, today the sport of sheiks, can no longer claim much of a hold on the average American sports fan. But the Kentucky Derby remains one of those events that transcends its sport, still a destination date--the first Saturday in May--for many of us who can't be bothered with the Santa Anita Derby or the Florida Derby or the Wood Memorial.

For those who can't wait another few weeks for this year's top crop of three-year-olds to convene at Churchill Downs, the perfect spring movie--"The First Saturday in May" by brothers John and Brad Hennegan--opens at theaters around the country today. It is a charming documentary about the run for the "Run for the Roses", as seen through the eyes of six hopeful trainers and their horses, each man hellbent on making it to Louisville on that special Saturday. While several of the trainers are quite successful, none command the mega-stables that can count on an entry or evenj several entries in the Kentucky Derby each year. For some of them, the Derby is at best a very occasional privilege and,for others, just getting to the starting gate of America's preeminent horse race is a once-in-a-lifetime dream. "I'm 48 and I want to go to the Derby before I die," says one of the trainers whose horse....well, let's not ruin it, since not all the horses make the Derby cut.

Given that the year is 2006 and one of the six horses is Barbaro, there is not much suspense about the outcome of the Derby itself--the largest winning margin in 60 years--and, of course, the tragic end when the great horse breaks down at the start of the Preakness two weeks later. But even the death of Barbaro--after an eight-month struggle that captivated the nation and broke its collective heart--can't obscure the beauty and joy surrounding these magnificent animals, the folks who love them and their Derby quests. As one woman owner of a certain age explains about the winner's circle, "When you get to my age, you don't have to go to the plastic surgeon. It's an instant facelift."

So's the film.
