In the beginning of the movie, when Annie Wilson (Cate Blanchett) is meeting with Wayne Collins (Greg Kinnear), she is wearing a black-and-white striped dress and a white blouse. In the next scene, when she is interacting with Buddy Cole (Giovanni Ribisi) she has the same blouse on, but now she is wearing a pink dress. At first you may think she could have gone home to change, but later that night when she is talking to her son she is wearing the black-and-white dress she had on earlier that day. If you watch this sequence there is nothing that distinguishes the scenes as different days: she drives to her son's school, stops by the gas station on the way home, and later that night speaks to her son. Overall, it's a pretty obvious and avoidable mistake.
