When Laura is standing outside the offices during the first earthquake, she calls out "Salma!" instead of the character's name, "Rose".
When Rose first enters the limo (approx 7 minutes into the film), she starts to close the door before the cameraman gets in. She then pulls her arm back and scoots over to let the person in before scooting back and closing the door.
Cameraman reflected on an elevator door as he follows Emma after the therapist sequence.
Right before the first earthquake, inside the limo with Hayek and Tripplehorn, you can see the shadow of a crew member's hand below the newspaper counting down from five and the earthquake starts.
When Rose walks into the bathroom, you can see the cameraman's hand at the bottom left-hand corner of the screen reaching out to hold the door as he follows her.
When the masseur goes into the film studio and up to the front desk, you can see one of the other cameras coming in on the right of him, just before the camera turns away.
When Lauren exits the house and goes to deflate Rose's tire, the cameraman's reflection can be seen on the back of the limo and then on Rose's car as he follows Lauren. Likewise, the cameraman is reflected a few other times on the limo - following Rose.
