After the visit to Victoria, Howard pours himself a coffee. The mug is in his left hand. Change camera, the mug is in his right hand.
Howard arrives home after work. In daylight. Inside the house, all the lights are lit. Less than two minutes later while he talks to Emily, the outside of the house (seen through a window) is a dark as night.
Madame Hawthorne blows out jack's candle. Victoria spits out her lower false teeth. In the next shot with false teeth on the table, she still has lower teeth in her mouth.
Howard hot wires a car. Typically, cars also have a mechanical lock in the steering column which prevents the turning of the steering wheel.
It is Halloween. There is a full moon. The last time there was a full moon on Halloween was all the way back in 2001.
Actually it was 2020, which is well within the realm of time when this movie could have taken place, as no date is actually given for when it is set.
