This typical but well-made action movie, which spawned numerous sequels, means to combine the best elements of the disaster movie with the hard-boiled attributes of traditional action-adventures. When a plane is hijacked to the Middle East by Palestinian terrorists, the Pentagon calls into action the Delta Force, an elite squad of highly trained commandos led by tough guy mainstay Lee Marvin and karate-action-star Chuck Norris. Their mission is simple: to thwart the terrorists and rescue the hostages, and the plot concentrates largely on just that, as the team uses its experience and fighting skills to get the job done. Its sometimes preachy patriotic bent occasionally gets in the way of the action, and Norris is a one-dimensional figure who at times takes himself too seriously, but his rapport with easygoing veteran Marvin moves the film over some implausible rough spots. While not a groundbreaking contribution to the genre, Delta Force impresses with its straightforward tough-guy style. --Robert Lane
