But, they stray from that formula a little too often and bog down the proceedings with unnecessary exposition and motivations that could be best
revealed during action sequences and not by bringing everything to a pace - killing halt.
The first, by George A. Romero, his wife and assistant director Chris Romero (née Forrest) and Tom Savini,
reveals that almost all the cast were friends, family or local Pittsburgh volunteers (even the mall was owned by personal friends of Romero), that the original script had a far bleaker ending (everybody dies) which was changed
during the shoot because the film was «too much fun» for it, and that the fourth film, should it ever get made, is a larger - scale affair set in a down - town area, with lots of
action sequences and an overarching theme of «ignoring the problem».
