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.
Towards the end of the movie when Adele is waving goodbye to Janet who's driving away in their Mercedes, Adele's left arm is behind her back. When they cut to her front, she's still waving but her left arm is to her side.
This film was released in 1999. Adele and Ann are at the beach drinking from Dunkin' Donuts cups. Dunkin' Donuts didn't come to California until 2015.
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.
