Revealing mistake: The blue framed window the girls walk in front of after exiting the VW bus parked along the curb is presented as part of an extension of the house, but not when there's a front view of the entire house. The windows are actually aligned with the front door. (00:11:44 - 00:15:00)
Continuity mistake: Where Richard parked the VW bus along the curb (front-end opposite a blue framed window and a chain-linked fence with hedges) did not match the bus' location when they went into their house. Also, when the girls entered the front door, the upper white part of the bus was barely visible (if at all) behind them and not visible to the left side of the door/screen, but was past the left side when Richard entered.

Continuity mistake: Venus' starts off with a burger in her left hand which immediately changes to a watermelon segment, while a cookie has now appeared in her right. She puts the watermelon down only for it to reappear in her left hand when the camera changes angle. The cookie has now disappeared. The camera switches again to show that the watermelon is no longer in her left whilst the cookie has returned to her right... which is swiftly replaced by her half-eaten burger. (01:07:00)
Continuity mistake: Venus and Serena are eating by the pool. As they talk with their dad, Serena's burger miraculously shrinks before being replaced by the cookie initially in her left hand. Then the shrunken burger reappears in her right hand and the cookie jumps back to her left. Finally, the cookie returns to her right hand. (01:07:00)
