As with all the best action films, this perfectly plotted and breathlessly paced adventure revolves around a simple plot: a mad bomber (Dennis Hopper) with a grudge wires an LA city bus to explode if it slows to under 50mph. Keanu Reeves is perfectly cast as the maverick cop trying to work out how to bypass the gridlocked city and defuse the bomb, Jeff Daniels is back at police HQ and, in her star-making role, Sandra Bullock is a luckless passenger who has to take the wheel. Jan de Bont’s first film as director is a masterclass in action movie-making and it stays in the fast lane for its entire running time, piling on the nail-biting set pieces, breathtaking stunts and also finding time for a winning line in humour and a spot of romance. Not to be missed.
