Corrected entry: When the mob guy that is after Diana is on the phone with the woman who tried to kill Diana, she is talking to her boss while getting her tire fixed. The boss guy is in jail and tells her to get rid of Julia, not Diana. Julia was the fake name she gave the real Sandy.
Corrected entry: When Bateman is in McCarthy's house, he asks her for her real name and she tells him it is Julie. Shortly after, TI and Rodriguez pound on the door and call out "Diana." For the rest of the movie, Bateman refers to McCarthy as Diana and, at least once, TI and Rodriguez refer to her as Julie.
Correction: Considering her character's love/hate relationship with the truth, this is not a stretch.
Correction: Pablo says you get "Julian" and get it done. Which is her partner's name. He never says Julia.
