Режиссёр проверил актёрский состав.

Режиссёр is in the nominative case, which is the usual case for the subject of a sentence.

In Режиссёр проверил актёрский состав, the director is the one doing the action, so режиссёр is the subject.

A few useful notes:

• режиссёр = director
• it is a masculine noun
• its dictionary form is already режиссёр

So the basic structure is:

Режиссёр = subject
проверил = checked
актёрский состав = the cast

In the past tense, Russian verbs agree with the subject in gender and number.

Here the subject is режиссёр, which is masculine singular, so the verb is:

• проверил = masculine singular past
• проверила = feminine singular past
• проверило = neuter singular past
• проверили = plural past

So:

• Режиссёр проверил... = The director checked...
• Режиссёрка проверила... or Женщина-режиссёр проверила... = A female director checked...
• Режиссёры проверили... = The directors checked...

Проверил is past tense.

Russian past tense is often easy to recognize because it usually ends in:

• -л for masculine
• -ла for feminine
• -ло for neuter
• -ли for plural

So проверил means checked, inspected, or reviewed, depending on context.

Проверил is perfective.

That means the action is viewed as completed: the director finished checking the cast.

The imperfective partner is проверял.

Compare:

• Режиссёр проверил актёрский состав.
  = The director checked the cast. / The director finished checking the cast.
• Режиссёр проверял актёрский состав.
  = The director was checking the cast. / The director used to check the cast.

So the perfective verb focuses on the result or completion of the action.

Yes, the direct object is in the accusative case.

But in this sentence, актёрский состав looks the same as the nominative form. That is normal.

Why?

• состав is a masculine inanimate noun
• for masculine inanimate nouns, the accusative singular is usually the same as the nominative singular

So:

• nominative: актёрский состав
• accusative: актёрский состав

The object is still accusative because of its role in the sentence, even though the form does not change.

Literally, yes, it is something like actor lineup or acting composition, but in natural English it usually means:

• the cast
• the cast lineup
• the acting ensemble

This is a fixed and common Russian expression.

Breakdown:

• актёрский = actor-related, acting, of actors
• состав = composition, makeup, lineup, membership

Together, актёрский состав means the group of actors involved in a production.

Both can work, but they are slightly different in style and emphasis.

• актёрский состав is a very common set phrase meaning cast
• состав актёров is more literally the composition of the actors or the group of actors

In many contexts, актёрский состав sounds more natural and idiomatic when talking about film, theatre, or TV.

So a learner should treat актёрский состав as a standard expression.

Yes, актёрский is an adjective.

It agrees with состав in:

• gender: masculine
• number: singular
• case: accusative (same form as nominative here because the noun is inanimate)

So:

• актёрский describes состав
• together they form a noun phrase: актёрский состав

You can think of it as:

• состав = lineup / makeup / cast
• актёрский состав = acting lineup / cast

Yes, it is important.

The letter ё is pronounced roughly like yo in york, though exact pronunciation depends on accent and surrounding sounds.

So:

• Режиссёр is pronounced approximately ree-zhi-SYOR
• актёрский is pronounced approximately ak-TYOR-skiy

A key point:

• ё is always stressed
• in writing, Russians often replace ё with е, but learners should know that the correct form here is ё

So you may sometimes see:

• режиссер
• актерский

But these are usually understood as:

• режиссёр
• актёрский

The stress is:

• режиссёр
• проверил
• актёрский
• состав

So the full sentence is pronounced approximately:

режиссЁр проверИл актЁрский состАв

Stress matters a lot in Russian, because moving it can make a word sound wrong or even like a different form.

Russian has no articles like a or the.

So Режиссёр проверил актёрский состав could mean:

• The director checked the cast
• A director checked the cast
• The director checked a cast

Which one is meant depends on context.

In many real situations, context makes it obvious. If the sentence appears by itself, English usually chooses the most natural option, often The director checked the cast.

Yes. Russian word order is more flexible than English word order because case endings help show grammatical roles.

The neutral order here is:

Режиссёр проверил актёрский состав.

But other orders are possible, for example:

• Актёрский состав проверил режиссёр.
• Проверил режиссёр актёрский состав.

These changed orders can sound more marked and may shift the emphasis:

• putting актёрский состав first can highlight the cast
• putting режиссёр later can emphasize who did it

So the original order is the most straightforward, neutral way to say it.

Yes.

Depending on context, проверил can mean:

• checked
• reviewed
• inspected
• verified

So Режиссёр проверил актёрский состав might mean the director:

• looked over the cast list
• confirmed who was in the cast
• reviewed whether the cast was correct or complete
• inspected the lineup of actors

The exact English translation depends on the situation, but checked the cast is the safest general translation.
