Forrest Gump is a movie heart-breaker of oddball wit and startling grace. There's talk of another Oscar for Tom Hanks, who is unforgettable as the sweet-natured, shabbily treated simpleton of the title. The Academy is a sucker for honoring afflicted heroes. In Hollywood, it's always raining rain men. Credit Hanks for not overplaying his hand. He brings a touching gravity to the role of an idiot savant from the South who finds strength in God, country, his childhood pal, Jenny (Robin Wright), and his good mama (Sally Field). When Forrest falls a few IQ points shy of minimal school requirements, Mama knows who to sleep with to bend the rules. Her son has a gift. As Forrest makes his pilgrim's progress from the '50s to the '80s, he becomes a college football star, a Vietnam war hero, a shrimp tycoon and even a father.
