In this film, Susan Sarandon calls Natalie Portman Pooh Bear. In Beautiful Girls (1996), Timothy Hutton calls himself Pooh Bear and calls Portman his Christopher Robin.
When Ann is auditioning for a movie role, the casting assistant calls for a "Karen Scarborough". Karen Scarborough is the payroll accountant for the film.
At the end of the movie, when saying goodbye at the airport, we can see a mother with her baby at the background who walks out the scene in the middle of the conversation between Adele and Ann. Some seconds later she is again in the same point. It occurs between 1:42 and 1:43 time of the film.
In the scene where Adele wakes up Ann to go see the sun rise, they are looking West out on the Pacific Ocean, but the sun would be rising in the East, not the West. To view anything in that direction, they would be watching the sun set.
Adele: [to Ann]
You are a beautiful girl with great potential. I'm not going to see your future as some nothing girl in a nothing factory in a nothing town! You are 14-years old. You have always had enough to eat. You have always had a roof over your head and if you stick with me you always will because I am your mother. I know what is best for you because that is my job. Plus, you're going to go to school in Beverly Hills which is only the best school district in the United States! And you'll be a child actor while you're still a child!
