Other mistake: Vivian and Bernard are standing outside of Albert's Open Spaces office taking to him when Tommy calls Bernard's cell phone. Bernard hands the phone to Vivian, who takes the phone and puts it next to her ear, upside-down, and begins talking to Tommy, through the speaker, and listening to him, through the microphone.
Other mistake: At several points in the film, Jude Law's American accent drops and you can hear his English accent quite lucidly; this is most noticeable when he says "Go back inside" to Naomi Watts.
Other mistake: Albert is narrating a letter he's writing. His character's name is Albert, but he signs it Alfred.
