Film Vs Movies – what’s right? Where do they come from?

As the UK, USA, Canada and Australia share more and more media with each other, there is increasing confusion over the “right way” to say certain things. Pavement or sidewalk? Ditch, Dyke, or Culvert? Cinema, Theatre, or Movies? Very confusing! If you are wondering which way to describe a film is “correct” I have bad news. They are all correct, in different places.
