The first example of Deus ex Machina that I found was the claw in the movie Toy Story. This machine comes down on the small alien toys and "saves" them, bringing them to a different life.

The second example of Deus ex Machina can be found in the movie classic, The Wizard of Oz. This happens when Dorothy can just magically get out of Oz by clicking her heels, just when she thought she would never be able to return home.

The third example of Deus ex Machina is found in
War of the Worlds, when after days of terror and
invasion the aliens suddenly start to die off because
they can not survive the bacteria that live on earth.
