Фильм озвучат сегодня.

Озвучат is the simple future form of the perfective verb озвучить.

In Russian:

• perfective verbs form the future with one word
• imperfective verbs form the future with быть + infinitive

So:

• озвучить → озвучат = they will dub / voice
• озвучивать → будут озвучивать = they will be dubbing / will dub (with a more process-oriented or repeated sense)

Here, озвучат suggests a completed action in the future: the film will get dubbed today.

Russian often uses the 3rd person plural with no stated subject to mean something like:

• they
• people
• someone
• the relevant people

So Фильм озвучат сегодня literally looks like They will dub the film today, but in natural English it is often better translated as:

• The film will be dubbed today
• They’ll dub the film today

This is called an indefinite-personal construction. The speaker either:

• does not know who exactly will do it,
• does not want to say,
• or simply considers it unimportant.

It is in the accusative, but for many inanimate masculine nouns, the accusative singular looks exactly like the nominative singular.

So:

• nominative: фильм
• accusative: фильм

That is normal.

Compare with a feminine noun, where the accusative often looks different:

• книга → книгу

So in Фильм озвучат сегодня, фильм is the direct object even though its form does not change.

Because фильм is not the subject.

The hidden subject is an understood they:

• (Они) озвучат фильм сегодня.

The verb agrees with that implied plural subject, not with фильм.

So:

• озвучат = they will dub
• фильм = the film (object)

Grammatically, it is active:

• (They) will dub the film today

But in meaning, English often prefers a passive translation:

• The film will be dubbed today

Russian often uses this active 3rd person plural without a subject where English might choose passive.

A more explicitly passive Russian version would be:

• Фильм будет озвучен сегодня.

That version sounds more formally passive.

So the original sentence is active in form, but can be passive in translation.

The perfective verb озвучить is used because the sentence presents the action as a single completed event.

The idea is not just that people will be working on dubbing, but that the film will get dubbed today as a completed result.

Compare:

• Фильм озвучат сегодня.
  = They will dub the film today. / The film will be dubbed today.
  Focus: completion/result

• Фильм будут озвучивать сегодня.
  = They will be dubbing the film today.
  Focus: process/activity

So the perfective form is very natural here.

In this context, озвучить usually means something like:

• to dub
• to voice
• to provide the voice track for
• sometimes to do the voice-over for

The exact English word depends on context:

• for a foreign movie translated into another language: dub
• for animation or characters: voice
• for narration: do the voice-over

So Фильм озвучат сегодня most naturally suggests that the film’s audio/voice track will be recorded or added today.

Yes. Russian word order is flexible, and changing it usually changes emphasis, not basic meaning.

For example:

• Фильм озвучат сегодня.
  Neutral; the film is the topic.

• Сегодня озвучат фильм.
  Emphasis on today.

• Озвучат фильм сегодня.
  Less neutral, but possible in context.

The original sentence sounds natural if the speaker is talking about the film and then says what will happen to it today.

No, not with озвучат.

Because озвучат is perfective future, it refers to a future completed event, not a habitual present action.

So it means:

• They will dub the film today
• The film will be dubbed today

If you wanted a habitual meaning, you would need a different form, for example with an imperfective verb and a different time expression.

The stress is on у:

• озвУчат

A rough pronunciation guide is:

• az-VOO-chat

That stress is useful to remember because Russian verb stress can move, and learners often want to know where to place it in future forms like this one.
