9. Terminator 3
The Terminator 3 is another film that has tons of mistakes in it. This is, ironically, another film that is starring Arnold Schwarzenegger. This movie also has Nick Stahl, Claire Danes, and Kristanna Loken in it. The 2003 film made a mistake when the tail number of an airplane continues to change. For example, before the plain takes off, the tail number is N3035C. When it is flying in the air, the number is N3973F. It then magically changes again when it lands.
