When Toby is in Jane's room for the first time, he picks up a bottle of wine, trying to get her to offer him some. He crosses the room and sets the bottle down on the mantel to the right of a vase, but, in the next shot, the bottle is on the left of the vase.
While Toby and Jane wait to cross a road as marchers go by, Toby is smoking a fresh cigarette; when they cross, it's gone and his hand is in his pocket.
About one hour into the film, when Toby and Jane are sitting on her bed talking, a shadow of the boom microphone is visible moving on the wall behind them.
