The true story lying behind the epic battle of the Wimbledon Men’s Final in 2008 between the sport’s titanic champion, grass court genius Roger Federer, and his recent rival, clay court overlord Rafa Nadal. It took place over five hours under darkening skies with lightning strikes and two rain breaks. Nadal took the first two sets, Federer the next two. Nadal says one of Federer’s passing shots in the fourth was the worst feeling he had ever experienced in tennis. The narration spins us back to their upbringing, born five years apart. You wouldn’t think it now but Federer had a vicious temper and frequently broke racquets on court. He had to learn to control his mind and co-ordinate his actions. He says he became surprised by his own creativity. You would think it was the Spaniard who had the fiery nature but he is sweetness itself. Nadal and Federer both became pro at 16 but Nadal needed to build up his strength. His vulnerability inadvertently gave him his greatest weapon – he returned late with a raised arm. It’s the greatest return since Jimmy Connors was playing. Both men come from close-knit families: Nadal is most at home on the island of his birth, Mallorca, cooking, sailing, fishing; Federer has a happy home life in Switzerland with wife and fellow tennis player Miroslava (or Mirka), and now, their four children. Their coaches and parents and that match’s umpire stress both men’s humanity and their desire to evolve: they make each other better. They also work hard. While Federer seems to look effortless he trains relentlessly. One amusing shot prior to their entering the court for one French Open final shows Nadal warming up like a prize fighter while Federer looks on, hands in pockets. It’s a misleading image. One commentator suggests that it was as though the tennis gods got together and made Nadal to compete with Federer – their games are utterly opposite, yet complementary. Federer is an artist who fights; Nadal is a fighter who also happens to be an artist. They are two strands of tennis DNA. The one is right-handed, the other a leftie. Nadal had lost the Wimbledon final the previous 2 years; Federer had been thrashed by him in Paris a month earlier, in three, the last set to love. Devastating. Home movies and interviews with both men and those around them and other players makes this illuminating and the footage of the 2008 match and others compel all over again as the differences between the merely brilliant players and the champions are teased out. Other great tennis rivalries are explored in passing: Evert/Navratilova, Borg/McEnroe – remember 1980?! When Borg retired McEnroe was not the same, Borg made him better. Navratilova makes the observation that those two guys are happiest in each other’s company; Evert says she and Navratilova made each other greater players. The true greats of the sport enjoy rarefied air and are the only other people on the planet to understand what it’s like up there. We are now living in what is probably the twilight of the greatest tennis era: this documentary shows us why. Directed by Andrew Douglas and based on material from Jon Wertheim’s book.
