In Clarissa's first visit to Richard's apartment, she gathers up some garbage and then drops the bags on the floor. Later when she opens the apartment door to leave, the garbage bags are already outside the apartment in the hall.
When Laura starts driving with Richie, the tops of the trees in their street are lit dimly sideways, as if the sun is rising or setting. The previous events however suggest it should be around noon. In the next shot, when they arrive at Mrs. Nash's house, the sun drops a hard and short shadow, more appropriate to the time of day.
Richard yells by the window, "Don't come near me!!" and, holding the handle, points his cane at Clarissa. In the very next shot, he's holding the other end of the cane with the handle is being pointed at Clarissa.
In the last scene between Laura and Dan, when Dan is lying on the bed and talking to Laura in the bathroom, we see a pack of cigarettes and a light on the night table. In some shots the lighter is next to the pack and in others it's on top.
When Julia puts her arm under the first stack of papers she removes from her mother's desk the bottom page is accidentally folded under her arm. When the camera angle changes the page is no longer folded.
When Clarissa is preparing the food for the party she is wearing a pair of green gloves. When Louis Water is telling her his story, Clarissa has taken one glove off and then in a next shot, when Louis Waters, leaves the house, Clarissa is still wearing the pair of gloves.
In the Virginia Woolf segment, Leonard Woolf is shown setting type for their press, Hogarth Press. In fact, Leonard's hands shook so that he could not set type, and it was Virginia who did the typesetting. Virginia found setting type calming, and said that it shaped her feel for words on the page, influencing her approach to writing.
