Bu filmi tekrar izlemek istemeden edemiyorum.

It is a very common Turkish pattern meaning I can’t help ..., I can’t help but ..., or I can’t stop myself from ....

So here, izlemek istemeden edemiyorum does not mean a simple literal sequence of without wanting, I can’t do. As a set expression, it means something like:

• I can’t help wanting to watch it again
• I can’t stop myself from wanting to watch it again

This is one of those cases where the whole pattern is more important than the word-for-word translation.

Yes, it looks like a double negative, and that is exactly why it can be confusing.

You have:

• istemeden = without wanting / not wanting
• edemiyorum = I can’t do

Together, in the fixed pattern -meden edememek, Turkish expresses the idea of not being able to avoid doing something.

So although the pieces look negative, the overall meaning is positive in the sense of being unable to resist.

A rough English parallel is:

• I can’t help wanting to watch this movie again

English also often uses a negative form to express this kind of meaning: can’t help.

Because film is the direct object of izlemek, and it is a specific object.

• bu film = this movie
• bu filmi = this movie, as a specific direct object

Turkish often marks definite/specific direct objects with the accusative ending. Here the accusative is -i:

• film → filmi

So Bu filmi tekrar izlemek means to watch this movie again, with this movie being a specific thing.

İzlemek is the infinitive, meaning to watch.

In this sentence, izlemek istemek means to want to watch.

So this part works like:

• Bu filmi tekrar izlemek = to watch this movie again
• Bu filmi tekrar izlemek istemek = to want to watch this movie again

Turkish very often uses the infinitive -mek / -mak where English uses to + verb.

Because istemeden and istemiyorum do different jobs.

• istemiyorum = I do not want
• istemeden = without wanting, or in this pattern, part of the idiom can’t help

Here, istemeden is not the main finite verb of the sentence. It is a converb/adverbial form built with -meden / -madan, which often means without doing.

So:

• istemek = to want
• istemeden = without wanting

In this sentence, it combines with edemiyorum to form the expression istemeden edemiyorum.

Edemiyorum comes from etmek, which often means to do or functions as a light verb in many expressions.

Here:

• edemiyorum = I cannot do
• but in the fixed pattern -meden edememek, it is best understood idiomatically, not literally

So you should not translate this sentence as if edemiyorum alone meant something like I can’t do it in the ordinary sense. In this structure, it helps create the meaning:

• I can’t help ...
• I can’t refrain from ...

That is why etmek is used here instead of another ordinary verb like yapmak. This is a set expression.

A helpful breakdown is:

• Bu filmi = this movie
• tekrar = again
• izlemek = to watch
• istemeden edemiyorum = I can’t help wanting / I can’t refrain from wanting

So the structure is basically:

• [Bu filmi tekrar izlemek] [istemeden edemiyorum]

Or more conceptually:

• I can’t help [wanting to watch this movie again]

That kind of chunking makes the sentence much easier to understand.

Because Turkish usually puts the main verb at the end, and longer verb phrases often come before it.

So Turkish builds up the idea first:

• Bu filmi tekrar izlemek = watching this movie again
• then adds the attitude toward it:
• istemeden edemiyorum = I can’t help wanting to

This is very normal Turkish sentence structure. English would usually distribute the meaning differently, but in Turkish it is natural to place the main verbal element at the end.

Bu filmi tekrar izlemek istiyorum simply means:

• I want to watch this movie again

That is straightforward and neutral.

But Bu filmi tekrar izlemek istemeden edemiyorum is stronger and more emotional. It suggests:

• the desire keeps coming back
• I cannot resist that desire
• I almost feel compelled to want it

So the second sentence is not just about wanting. It is about being unable to stop yourself from wanting.

No, that would change the structure and would not express the same idea.

The important pattern here is:

• X istemeden edememek = to be unable to help wanting X
• more generally -meden edememek = can’t help doing

In your sentence, the thing you cannot help is the wanting:

• izlemek istemeden edemiyorum = I can’t help wanting to watch

If you changed the verb forms randomly, the meaning would either become unnatural or simply different.

Yes. The pattern -meden edememek is very productive.

Examples:

• Gülmeden edemedim.
  I couldn’t help laughing.

• Sormadan edemeyeceğim.
  I won’t be able to help asking.

• Merak etmeden edemiyorum.
  I can’t help being curious.

So your sentence uses a very useful pattern that you will see often in Turkish.

Strictly speaking, it is about the desire, not the action itself.

• izlemek = to watch
• izlemek istemek = to want to watch

So the sentence says that the speaker cannot help wanting to watch the movie again.

If you wanted to say I can’t help watching this movie again, that would be a different idea. This sentence is specifically about the repeated urge or desire to watch it again.
