Translation guide
The English word "film" covers several distinct concepts: a movie, a thin layer or coating, photographic material, and the medium of cinema. This guide helps learners choose the right Japanese expression for each meaning.
Referring to a movie shown in theaters or on TV, or the art form.
The most common and general word for a movie or film. Used for both the medium and individual works.
昨日、面白い映画を見ました。

He is a film director.
Can mean a movie, but often sounds old-fashioned or technical. More commonly used for photographic film or thin layers.
このフィルムは白黒です。
This film is in black and white.
A loanword from English, used casually, especially in compound words or when referring to home videos.
週末にホームムービーを見た。
We watched a home movie on the weekend.

Sometimes used in artistic or technical contexts, e.g., 'film as a medium', but 映画 is more common.

the history of film
When referring to a thin layer, do not use 映画 (movie). Use 膜 or 薄い層. Using 映画 for a layer of oil would be nonsensical.
映画 is the everyday word for a movie. フィルム is more technical or old-fashioned, often referring to the physical film strip. In modern Japanese, 映画 is almost always the better choice for 'movie'.
