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 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.
