Other mistake: The hospice male nurse Juan Is credited as Julio in the credits at the end.
Revealing mistake: After exercising, Valerie is in bed watching the news, then the scene changes to a shot of her house showing a Honda Accord at the 2002 meeting but this model did not get released until 2008.
Continuity mistake: During his second interview with Jack, Stone tilts his body to the right in the front shots, but remains straight in the back shots.
Character mistake: When Johnny and Cleo leave the Chateau and head for Vegas, they are shown getting on the 101 freeway North (in Hollywood) and are coming from the east and turning right onto the freeway. The Chateau is in West Hollywood so to turn onto the freeway where they did, they would have come from the west.
Factual error: In golf scene, Kevin Spacey is supposed to be playing golf in St. Andrews. The intensity of sun and the surrounding fauna suggests they are actually playing on a course in the mid latitudes of the US. (00:11:30)
Other mistake: In the middle of the movie, there is a scene with the two moms on the couch talking. One mom (red hair lady) wears a necklace with a charm that says "love." There are two camera shots in this scene, one looking directly at her, and another from over her left shoulder. Depending on the shot, the 'love' charm is either visible or tucked under the top of her shirt. This swaps back and forth.
