There"s a grain of truth in Jon Turteltaub"s comedy, as Jamaica did compete in the four-man bobsleigh at the 1988 Winter Olympics in Calgary. But the quartet were soldiers, not failed sprinters. Furthermore, they weren"t coached by a disgraced American gold medallist and weren"t given the cold shoulder by their fellow competitors. Even the structure of the competition is wrong, as teams make four runs across two days not three on consecutive days. It"s still good fun, though.
