You know that old dramatic principle of suspension of disbelief? You'll have to rely on it for this box-office smash, but you won't be disappointed. Harrison Ford plays a U.S. president who single-handedly employs his rigid antiterrorism policy when a band of Russian thugs hatch a mid-flight takeover of Air Force One. Gary Oldman, who chews the scenery as the lead terrorist, will shoot a hostage at the slightest provocation. Glenn Close plays the sternly pragmatic vice president who negotiates with Oldman from her Washington seat of power. If you can believe that the aircraft's pressurized cabin can sustain hundreds of rounds of machine-gun fire, you'll buy anything in this entertaining potboiler, especially thanks to Ford's stalwart heroics and some nifty special effects. Director Wolfgang Petersen (Das Boot) keeps the action moving so fast you won't be sweating the details. Don't forget your parachute! --Jeff Shannon
