When clearing after dinner, Maura spills a glass of wine on herself. A certain actress/continuity guru had to sheepishly tell the director that she had been wrong about a wardrobe change, and the line was added to make sense out of what would have been a sudden unexplained change in the finished film.
The film was supposed to take place during a cold and rainy December before Christmas. Production actually took place in mid February in 2012---during one of the warmest Februarys on record.
