Bill and Ted’s Excellent Adventure (1989)

In a classroom scene from this 1989 sci-fi comedy about 2 highschool buddies who travel through time, the blackboard is seen with a collection of words and names scribbled on it. In the next scene however, not only does the handwriting on the board change, but so does the spelling of the name GENGHIS KHAN.

In the 1991 action sci-fi classic, John Connor (Edward Furlong) helps his mother, Sara Connor, escape from prison with the help of the Terminator (Arnold Schwarzenegger). They boost a police car as a getaway vehicle when the T-800 android gives chase.
