Quentin Tarantino's sanity has been debated more than once in the past couple of years. In fact, nearly everyone who has been questioned about his first film in six years, ''Kill Bill'' -- a production that was so prolonged, freewheeling, and downright goofy that the crew called it ''the traveling circus'' -- has responded with a bemused question of their own. And that question is: Has Tarantino, the star filmmaker behind such cultural touchstones as ''Reservoir Dogs'' and ''Pulp Fiction,'' lost his mind?
''He has this free style and it's terrific, but the movie was totally out of control,'' says Uma Thurman, who stars as an assassin called ''The Bride'' in ''Kill Bill,'' a two-part revenge thriller (''Volume 1'' opens Oct. 10, followed by ''Volume 2'' on Feb. 20). ''It was a wild ride. But that's Quentin.''
