When Ruby's mom, Babs, steps up to bowl for her first time the scene cuts from showing three or four pins at the end of the lane to all ten standing up.
The outside view (establishing shot) of the bowling alley shows the business sign and mid-century modern building of the "Land Park Bowl", located at 5850 Freeport Blvd., Sacramento, California. Inside, the decor and a clear sign on a pin-removing arm that comes down at the end of the alley in one scene shows the "Mission Hills Bowl", at 10430 Sepulveda Blvd., Mission Hills (Los Angeles), California.
When Eileen accidentally throws the bowling ball backwards, it bounces like a regular ball.
Eileen is bowling on lane 21, but when Louis replaces her ball, he's at lane 22.
The check Louis receives for winning the contest is dated September 19, 2001. However, the exterior shot of the bowling alley the girls bowl at advertises karaoke on June 30 and July 2, respectively.
