After Bethany (Shaniya Brown) stands near the fridge drinking her wine, she looks back at the table she has set for dinner. When filming her view point of the kitchen table the wine bottle was accidentally left on the table. Clearly, the bottle could not be there, since she just gotten it out of the fridge. The bottle had to be digitally removed from the table in post.
Originally, "Stages" was to take place in a more opened and spacious house. The day before the shoot that location fell through without a real reason to why. That night the team got together and decided to use one of the producer's homes, instead.
Shaniya Brown, who plays Bethany, actually wears two different striped dresses in the film. The 2nd dress had the stripes arranged in a different order.
