A great on set visit report at
Filmforce reveals that Spielberg actually owns one of the few surviving original scripts to Orson Welles 1938 War Of The Worlds broadcast! (He claims its the only one, though I am aware of one other earlier surviving draft.) Don't expect any great connection between his movie and the broadcast, but nice to know he is aware of the broadcast and it's part in the history of The WOTW.
