Factual error: Gallaxhar scans the galaxy to find the missing quantonium. The scanner zooms in on earth, showing it to be very close to the center of the galaxy. Earth is actually nowhere near the center of the galaxy; it's located much closer to the outer edge.
Factual error: The TV station in Modesto, CA had call letters starting with a W. All broadcaster call letters west of the Mississippi start with a K.
Continuity mistake: It's shown in many scenes that the robot Gallaxar sends isn't particularly quick moving when it walks. But when it's chasing Ginormica around the city, even though Ginormica is sprinting away, it can catch her far more quickly than its speed would allow. It doesn't suddenly speed up - in the shots when the camera focuses on the robot again, you can still see it moving slowly.
The President of the United States: Somebody think of something, and think of it fast!
Question: If Derek values his career to Susan, then why did he ask her to marry him in the first place?
