About 35-40 minutes into the film, Jules and Jess are at the bus stop. Pinky's future in-laws drive by in the Jaguar with nothing in front of them. When the camera shot moves back as they enter the bend, another car has appeared in front of them.
The director's family stars as extras in the movie. For example, when Pinky and Teets are getting engaged, just before the cell phone rings, a person is shown in a close up. That is the director's aunt. Even the director is shown at the party after the engagement.
