Compared meaning: a movie shown in a theater or at home (noun).

比较义项：电影（名词）。

• picture

  Old-fashioned word for a movie, mainly used in nostalgic or fixed expressions (like an older person recalling 'seeing a picture'); rarely stands alone in modern everyday speech.

  较为老式的“电影”说法，主要出现在怀旧或固定的表达中（比如老一辈人说“去看一场 picture”），如今很少单独用于日常口语。

  Grandpa always called going to the cinema 'seeing a picture'.

  爷爷总是把去电影院说成“seeing a picture”。

• movie 本词

  The everyday, casual American English word for a film, natural in relaxed invitations like suggesting one at home with snacks.

  美式英语中日常、随意的“电影”说法，很适合用在轻松的场景中，比如邀请别人在家一起看电影、吃零食。

  Wanna grab some popcorn and watch a movie tonight?

  今晚要不要买点爆米花，一起看一部 movie？

• film

  Common everyday word for a movie in British English; in American English it sounds more formal or artistic, and pairs naturally with words like 'documentary' or 'festival'.

  英式英语中日常使用的“电影”说法；在美式英语中则显得更正式或更具艺术色彩，常与 documentary（纪录片）、festival（电影节）等词搭配。

  The documentary film received praise from critics at the festival.

  这部纪录 film 在电影节上获得了影评人的好评。

Picture, movie, and film can all mean a movie. Picture is old-fashioned, mainly in fixed phrases. Movie is the everyday, casual American word. Film is everyday in British English, but sounds formal in America. Picture's 'photo' sense and film's 'thin layer' sense are not compared.

这三个词在“电影”这一义项上意思相近，但语体和使用习惯不同：picture 偏老式、多见于固定搭配，movie 是美式英语中最常用的口语词，film 在英式英语中是日常用词，在美式英语中则偏正式或艺术化。这里不比较 picture 的“照片”义，也不比较 film 的“胶片、薄膜”义。
