Hi, MichaelI haven't seen the film since it was first released aeons ago, but I think I remember the glimpse of Coppola and crew from the original cut. My assumption at the time was the scene had two purposes:
First, to comment on the "dinner-time TV news" nature of the war which brought us "live up to the minute death in living color" into our living and/or dining rooms every evening and
Second, to allow FC a cameo in his film.
Could be wrong, but that's the way I recall it.
