Revealing mistake: When Detective Boyd receives the package at the end of the movie, the package is not even addressed to him, but rather to a Jim Clark, 123 Chapman Lane, 96561 Lotus, CA. Which is, as you might guess, a sample package label. One of the top results when you Google "UPS shipping label", or whatever the lazy production department people looked up without bothering to edit it. (01:23:35)
Revealing mistake: Boyd brought Dr. Mackles to the location where he escaped the police hunt. Meanwhile, he rummaged through the rest of the place. In a closet, he found a newspaper with an article that talks about the evil South African CEO. In the first paragraph, because the rest is filler text about a completely unrelated topic (the answer about an inheritance question from the advice column of the Moneywatch website). (00:58:50)
