Continuity mistake: In the scene when Grandma's car breaks down when Grandma and Sage are on the way to Sage's appointment, Grandma doesn't have her purse when she gets into the stranger's car. In the next shot, when they exit the back of the minivan, Grandma now has her purse around her neck and by her side.
Factual error: A 1955 Chevrolet is parked in front of Lily Tomlin's 1955 Dodge. Its license plate reads "528 GPR." California license plates did not begin to use combinations of three numbers followed by three letters until 1969. The "528 GPR" plate would have been issued circa 1975 and originally had yellow letters on a blue background. For the movie, the blue background was repainted black so the colors were appropriate for 1955. However, an actual 1955 plate would have three letters followed by three numbers.
