Character mistake: When Laurie and Annie are on their way to babysit, and they see Annie's dad, the cop, as soon as they pull up to say hi and roll the window down, he mixes the two names up, and calls Laurie Annie, and Annie Laurie. You'd think he knows his own daughter's name. (00:32:10)
Character mistake: When David and Nick meet at the bar, a woman can't help but stare at the camera twice.
Character mistake: When Dr. Elkins is measuring the Killer Whale, she says "111 centimeters" followed immediately by "68" (centimeters). But her arm spread shown when she says that is not 111 centimeters - about 3.6 feet (1+ YARD wide). It's more like 2 feet. The "68 centimeters" is actually more accurate for the shot though: 26 inches, which is shown.
Character mistake: Dr. Bessner tells Linnet that the Eastern statue she'll see at Abu Simbel is 'the vocal statue', which emits a sound at sunset. The statues the doctor mentions are the Colossi of Memnon, over 500 kms north of Abu Simbel, so the movie here mixes up two very different monuments. (00:49:30)
Character mistake: During the photo shoot scene in Times Square the model actress Lisa calls the other model by her real name, Darlanne, instead of her character name Lulu. It happens when she is pulling her hair for the photos.
