Perhaps the only thing less likely than a Jamaican bobsled team is a Hollywood film inspired by the true story of the crew that competed in the 1988 US Olympics. Not that this sticks closely to the facts; instead, it's another Rocky-style sports movie about the underdogs who achieve public recognition and self-respect. Travelogue shots of happy Jamaicans dancing in the sun give way to patronising comedy as slobbish ex-coach Candy is cajoled into teaching four novices. The missing ingredients are snow and ice, but there's plenty of this when the scene shifts to Canada. In his prime, co-writer Michael Ritchie might have turned this into a caustic Downhill Racer or Bad News Bears-style critique of professional sporting values. Director Turteltaub, on the other hand, patronises both characters and audience with daft knockabout humour, tear-jerking sentiment and racial stereotyping which skates on very thin ice.
