Trivia: The scene where Barbara crashes the car into the tree wasn't scripted originally; an accident that put a large dent in the car before the scene was shot prompted George Romero to re-write the scene in such a way that the dent is justified.
Trivia: Duane Jones was the first African American to play a lead in a horror film. He also taught at and became the head of the Theatre Department at Old Westbury college in Long Island, New York. He remained there until he unfortunately passed away in 1988.
At the beginning, Barbara finds a corpse at the top of the farmhouse stairs with its face partially eaten away. Later, when Ben drags the corpse into another room we get a fleeting glimpse of its face and it shows no sign of decay of any sort.
