Continuity mistake: The woman has blood from the corpse upstairs dripping on her right hand. In the very next shot her right hand has no signs of blood, and she's shown wiping non-existent blood from her left hand. (00:16:14)
Other mistake: Ben drags the body of the ghoul he killed in the house out the kitchen door. As he drags it out you can see he leaves it on the porch and lights it on fire, which would certainly set the wooden porch on fire and probably the rest of the house. But, once the flames are huge, you will see that the body has moved down onto the grass. But Ben never pushes it down off the porch. (00:19:45)
Other mistake: When Ben smashes the face of the ghoul trying to walk through the kitchen door, he comes back in and locks the door. But, when he drags the body of the ghoul he killed in the house out that same door and lighting it on fire, he runs back in, slams a small table against it but never re locks it. So until he boards it up, that door is left unlocked. That little table wouldn't stop anyone. (00:18:45 - 00:20:00)
Visible crew/equipment: When Barbara is running around the house to find a way in, someone backs up (possibly with a camera in hand) behind a tree.
Answer: Yes, director George Romero announced in 2015 that he had rediscovered some 16mm working footage that never made it into the movie, including a full 9-minute sequence (a jump-cut of the basement scene) featuring the largest zombie attack in the film. Although Romero died earlier this year, film legend Martin Scorsese was said to be overseeing the film's restoration including the found footage.
