By George, He Got It: George Hamilton, who hasn't had a role in a feature film since 1981, almost didn't end up in "The Godfather Part III." Hamilton, 51, plays a WASP lawyer who sets up a deal for the Corleone family with the Vatican Bank. Hamilton said in the January issue of Vanity Fair that his agent at first turned down the role because he had been told it would be a cameo. "You did what?" he recalled telling his agent. "We're talking about 'The Godfather' here." Finally, Hamilton called director Francis Ford Coppola in Italy, and Coppola assured him that he still wanted him in the movie.
