The Shining 

In the highly successful movie, The Shining, Jack Nicholson had an improvised moment of pure gold. It almost didn’t make the cut, but luckily it did since it turned out to be one of the most famous lines from the movie.  

When Jack is trying to break down the door with an axe to try to get to his wife, the tension is palpable. Nicholson had to destroy nearly 60 doors to finally get the visuals for the scene perfectly. It comes as no surprise that his ad-libbed “Here’s Johnny” adds a moment that escalates the terror, making it perfect for both on and off camera.
