Revealing mistake: In the last scene of the episode, Angel kicks the guy out of the glass building. This guy's a vampire, and you can see his reflection in the glass windows. Vampires aren't supposed to have reflections.
Visible crew/equipment: Livia and Junior have a chat about Tony while waiting in line for a movie matinee. It then cuts to the Soprano house, and in the next overhead shot of Tony sprawled on his bed, we can see the T-mark on the floor near the door. In a moment, Lilliana knocks and enters to remind Tony of his appointment.
Continuity mistake: During the beginning before the opening credits, C.J. is briefing the press corps on the bus. In the outside shot of the bus, C.J. has her left arm resting on a rail, towards the door. When the shot changes to inside, C.J. has her right arm on a rail towards the driver. (00:01:15)
