Defying the whole we-are-not-alone thing, Steven Spielberg takes a moment on Close Encounters’ sound stage in one of the cavernous hangars at Alabama’s Brookley Air Force Base. Spielberg overhauled Paul Schrader’s original draft to such an extent that Schrader removed his name from the script, leaving the director with one of his two screenplay credits (A.I. is the other). Schrader’s drafts were called ‘Kingdom Come’ and ‘Pilgrim’. ‘The Third Kind’ of the eventual title stemmed from astromer J. Allen Hynek’s The UFO Experience: A Scientific Inquiry and represented contact with extra-terrestrials. The fourth kind is the bit where they blow up The White House.
