When Olga walks into the house to look for Laura, she is wearing black flat shoes. When she enters the house, she is wearing black high heel pumps.
When Mark Higbie encounters a spider at the top of the stairs at the Lockwood Winery, it changes from a gray tarantula to a phony-looking black spider in the next shot.
At 41:27 into the film, Leigh (not Lee, as it says in the captions) introduces "Jeff", her sister's significant other.
Later, at 44:30 when "Jeff" enters the room, either the captioning crew got it wrong, or Leigh calls him "Jim". It is actually very difficult to hear what Leigh actually says in this scene.
The family members are listed as "Lockwood" in the credits, but are called "Lockridge" in the film.
