Deus ex machina

Deus ex machina is a common term used in literature and movies. It means "god from the machine" and it refers to the way a problem or situation can be solved in an unexpected or sudden way. Imagine you are watching a movie and the main character is stuck in a difficult situation. Suddenly, in the last few minutes of the movie, a giant robot appears out of nowhere and helps the character out of the difficult situation. That is an example of deus ex machina - god from the machine!
