Part of the fun in watching a movie is immersing yourself in another world. However, part of the fun in watching movies can also be spotting production errors such as the coffee cup spotted in a “Game of Thrones ” episode or an airplane in the sky during a scene in “Pirates of the Caribbean.”

In the latest movie, “Cats,” actress Judi Dench is supposed to be a car, yet her human hand is clearly visible in one scene. While that doesn’t detract from the story, it does make the movie more interesting to watch even if the story isn’t that interesting.

Perhaps Hollywood should simply show more flubs in “Cats” to make the movie worth watching since nobody seems interested in seeing it the way it is right now anyway.
