Bu filmi iki kere izledim.

Because bu filmi is a definite direct object: it means this film, a specific film.

In Turkish, a specific direct object usually takes the accusative ending. For film, that becomes filmi.

• Bu filmi izledim = I watched this film
• Film izledim = I watched a film / film (non-specific)

So the -i on filmi is not part of the dictionary form of the noun; it is a case ending.

When bu is used directly before a noun, it stays as bu. The case ending goes on the noun, not on bu.

• bu film = this film
• bu filmi = this film (as a definite object)

But if bu stands alone as a pronoun, then it does change:

• bunu izledim = I watched this

So:

• bu filmi = this film
• bunu = this one / this

İki kere means two times or twice.

It is a frequency expression:

• iki = two
• kere = time / occasion

So Bu filmi iki kere izledim literally means I watched this film two times.

Very common alternatives are:

• iki kez
• iki defa

All three are natural.

In Turkish, nouns after numbers are normally singular, not plural.

So you say:

• iki kere
• üç film
• beş gün

not:

• iki kereler
• üç filmler
• beş günler

This is very different from English, where we usually use the plural after numbers.

İzledim breaks down like this:

• izle- = watch
• -di = past tense
• -m = I

So:

• izle-dim = I watched

Because of vowel harmony and normal sound patterns, the form appears as izledim.

Related forms:

• izledin = you watched
• izledi = he/she/it watched
• izledik = we watched

Because Turkish is usually a subject–object–verb language, and the verb often comes last.

So this sentence is structured like:

• Bu filmi = this film
• iki kere = two times
• izledim = I watched

Literal order: This film two times watched-I

That sounds strange in English, but it is normal in Turkish.

Turkish often leaves out the subject pronoun because the verb ending already tells you who the subject is.

In izledim, the -m means I.

So:

• Ben bu filmi iki kere izledim = I watched this film twice
• Bu filmi iki kere izledim = I watched this film twice

Both are correct, but the second is more natural unless you want emphasis on I.

The Turkish -di past tense mainly expresses a completed action in the past. In English, depending on context, it may correspond to either:

• I watched this film twice
• I have watched this film twice

In many learning contexts, the safest basic translation is I watched this film twice, but real usage can overlap with English present perfect depending on context.

Yes, Turkish word order is flexible, but the basic order here is very natural.

Standard neutral order:

• Bu filmi iki kere izledim.

You can move parts around for emphasis, for example:

• İki kere bu filmi izledim.
• Bu filmi izledim iki kere.

These may sound more marked or conversational depending on context. For learners, Bu filmi iki kere izledim is the best neutral pattern to remember.

Yes. A very common alternative is seyretmek, which also means to watch.

So you could also say:

• Bu filmi iki kere seyrettim.

Both are natural. In many contexts, izlemek is a very standard choice for watching films, TV, videos, and so on.

Turkish does not have words exactly equivalent to English the and a/an.

Instead, definiteness is often shown by context and grammar. In this sentence, definiteness is shown by:

• bu = this
• the accusative ending in filmi

So bu filmi already clearly means this film, a specific one. No separate word for the is needed.
