в чем разница между movie и film?

Question

Answer

Most people use these two words interchangeably.

But in reality, there is a difference:
   - The movie is the CONTENT/DATA.  
   - The film is the MEDIUM that stores/contains the content.  
In other words, the film contains the movie.  Playing the film plays the movie.

Analogs:  
A vinyl/record contains one or more songs.  
A CD contains many songs.  
A tape contains many songs.  
A DVD contains a movie.

Answer

The first is Americal English, the second is British English.
