'Fat City':A Small,Fine FilmAt th* Capri“Fat City” breathes the life of the boxing ring, the small* time ring where the takings, even If you’re a winner, aremostly lumps.Director John Huston’s solid, gritty film takes a tough, 'and sympathetic, look at the life of a winner turned loser. Seedy hotel rooms, twelfth-rate bars, an almost ludicrous hoping against hope “to get back in shape” at last, scrounging for a living doing stoop labor — that’s the life of Billy Tully.Stacy Keach plays Billy from the inside out, seeming to take on the entire character of the scraggly but gutty boxer — at 30 over the hill but refusing, through a haze of booze and lost jobs, to give up.Director Huston has man* aged to steer the entire cast into using the same technique of realism. Jeff Bridges as the promising young fighter plays his role with just the proper amount of dttmb-but* happy naivete. But probably the best role after Reach’s is that of Susan Tyrrei, stunningly real as the drunk* en Oma, a lush who makes Idiotic drunken talk sound so real it could be coming from the next bar stool.Huston's setting — Stockton, Calif., and environs — is acharacter in itself. He uses grubby hotels and scruffy street characters to background his story, setting the unreality ofthe dreams of these small-timesagainst the shabby reality of their lives and the alibis they I live on.All of their lives are like Billy Tully’s. In one stabbing insight, he sums it all up: “Before you can get rolling, your life makes a beeline for the drain.” ,Huston makes author Leonard'Gardner’s point clear: It’s hard to tell the winners from the losers at this level of the fight game. The only winners in “Fat City” — an old jazz term signifying the good life — are John Huston, for having made a small and fine film, and the viewer. —Joan Bunke
