Like Tupac and Jim Croce, Stanley Kubrick -- who directed just three movies in his last two decades -- is slowly becoming more prolific in death than he was in life. First came Eyes Wide Shut, which opened four months after Kubrick's 1999 passing. Then there was A.I., a longtime project ultimately made by Steven Spielberg. And now two more movies are on the way. One, a '50s thriller called Lunatic at Large, emerges from an arcane corner of the filmmaker's legend having to do with a treatment he commissioned from his Paths of Glory co-screenwriter, pulp author Jim Thompson, and then misplaced. For some 40 years the manuscript was considered MIA -- until producer Philip Hobbs (who, as Kubrick's son-in-law, worked closely with him on Full Metal Jacket and other projects) dug it up recently while sifting through some old papers. According to Hobbs, Lunatic will, ''with luck...be in production in late 2004.'' Ditto God Fearing Man, an early-20th-century drama that would be the first original Kubrick-penned script produced since 1955's Killer's Kiss. No word on who'll star or direct. ''Stanley was involved in both projects in 1956 and 1957,'' says Hobbs, ''and he never forgot either.''
