The director later explored a slave revolt and trial in Amistad (1997) and won his second Oscar for the chillingly realistic war drama Saving Private Ryan (1998). He subsequently examined a ghastly future world of neurotic humans and sentient robots (the result of a collaboration with Stanley Kubrick) in A.I. (2001), for which he also wrote the screenplay, and portrayed another dark future in which crime is detected and stopped before it is committed in the allegory-thriller Minority Report (2002). He turned to a lighter, more comic vision in his tales of a young imposter and his implacable pursuer in Catch Me If You Can (2002) and of an Eastern European stranded in New York's Kennedy Airport in The Terminal (2004). By the early years of the 21st cent., Spielberg was mainstream Hollywood's most famous, influential, and successful director.
