Audio problem: When Vince and Mike pull the tabletop out from under the car, while Roy is under there with Mrs. Merkle, we hear the audio of Roy loudly saying, "I'm telling you right now, we're gonna have to brace this thing well, this thing will...," but what's oddly funny is that the dialogue is dubbed right over Roy saying, "Wait, wait, let me check her over...," which is a neat trick that he can say both lines at the same time.
Audio problem: At night when MacGyver and Jack are sneaking past the guards behind a mule, we see about 8 to 10 light bulbs hanging overhead. MacGyver later pulls the cord down and all the lights begin to pop. There are about 16 pops, many more than there were bulbs on the cord. (00:24:50)
