Brianna's top changes from white in the living room around the 40 minute mark to black when the group is making their way to the cellar door @41:17 and back to white when in the cellar room.
Dottie gets into her four door compact sedan (Ford Escort) at 5:30 which features through her driving to the property but at 6:03 she is driving a two door hatchback. The hatchback remains Dottie's car through the rest of that scene. Next time she drives to see Brianna on set (11:50), she's in the four door sedan but cutting to the property scene (13:48) she has the hatchback again. For the rest of the movie, it's the four door sedan.
