Visible crew/equipment: Just shortly after Ellen lets Paige in, when Ellen stands at the counter, Paige mentions handcuffs, and then Ellen's boyfriend comes out. As the camera pans to the right, you first see a streak of light in the middle and as the camera continues to move four or five stage lights can be seen. This can be seen on the season 2 DVD set very clearly. (00:09:25)
Continuity mistake: In the scene where Ellen goes to Susan's room after Richard makes a pass at her, she has her jacket in her hand when she enters the room. When Ellen leaves the room hurriedly, she leaves without her jacket, but when she is in the hallway about to go back to Richard's room, she has her jacket in her hand.
Continuity mistake: When Ellen tells her friends that she is gay, she starts to digress. There is a bunch of wine glasses on the counter directly behind her. In several shots of the friends around the table, there are no glasses to be seen, but when Audrey says "I thought you had something important to tell us", she is holding a glass of wine. When you next see Ellen, the glasses are no longer on the counter, and the glasses are actually on the coffee table a moment later when the friends get up to leave. Yet no one actually served the wine out or got up to get any from the counter.
Other mistake: The establishing shots of Buy The Book make it clear that there is an optometrist next to Buy The Book, but in the season three episode premiere Shake Rattle and Rubble, a major plot point is that there is a dry cleaners next to the store, which is not only wrong but impossible.
Visible crew/equipment: Right after Ellen answers the door there is a shot of Paige, Spence and Joe. You can see the edge of the set, the lighting and some of the props behind and off to the side of Paige. This occurs again during the party in the same location. A stagehand can be seen in this instance.
Continuity mistake: There is a large black cue ball on a wooden base beside the staircase at the bookstore When the crowd rushes past it it gets knocked to the floor and bounces away, but immediately after in the next shot it is back on the base, then it is gone again.
