Steven Spielberg’s Raiders of the Lost Ark (A+) is a rollercoaster ride through history as archeologist protagonist Indiana Jones races against time to find the Ark of the Covenant before the Nazis do. It is said to have powers that will protect an army; in the wrong hands, it could help evil forces conquer the world. Spielberg gives his grizzled hero simple tools (a bullwhip, an occasional map), a spunky girlfriend (Karen Allen) and a globetrotting trip from Peru to Egypt and beyond as he chases antiquities. Harrison Ford is at his very best in this role; and the effects and stunts are epic. This is one of the great modern adventures, told with wide-eyed wit and wisdom.
