Monsters vs Aliens (2009) - 6 mistakes

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.

Continuity: When Susan comes back to save her friends, she passes through the holes she made in the steel doors before. Ginormica is supposed to be 50 feet tall, but when Susan passes through the holes in the UFO, her size is 1/3 of the holes she made as a giant.

Continuity: 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.

Continuity: We see many people running from the alien robot on the bridge. We then see Ginormica, and behind her the people have disappeared.

Other: At the end of the Golden Gate Bridge scene, B.O.B. does not get off the bridge before it collapses and no one goes back to save him. But he is seen on the remaining half of the bridge looking down on the scene.

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.
