This is optional but you should always capitalize the first letter of every word except for prepositions. But if you’re writing a research paper, only the first letter of the first word (and proper nouns) should be capitalized.

This can be connected to the previous sentence.

This is actually the best way of studying English.

I kept it as a wish since that's how you wrote your sentence. However, a more direct option would be, "I want to watch any movie in English."

It needs an article.

I want to bemaster English master because I want to watch "Pirates of cthe Carribean" without subtitles.

Use phrases "I want to [verb] + [object]" to sound more natural. Requires an article after "of" in the name of movie, and also subtitles needs to be pluralized.

I wish iant to be able to watch any movie in English.

Similar format above: Use phrases "I want to [verb] + [object]" to sound more natural. Could alternately say "I want to watch any movie in English" however this sentence is less natural.

Thanks tofor the help.

'Thanks for' is another standard framing.

I want to bemaster English master because I want to watch "Pirates of carrithe Caribbean" without subtitles.

It is more natural to use "master" as a verb in this sentence.

So, I will write English texts on the internet.

Using "will" shows that this is your plan, and you will do it for a long time.
Each piece of writing is a text, so making "texts" plural shows you will write many.
There is only one internet.

I know it's a hard way, but I will do it.

I think you mean that writing texts is a hard way to master English?

I wish i watchant to watch any movie in English without subtitles.¶
I want to watch and understand any movie in English.

A native speaker would say "want" instead of "wish."
"Want" is a much more general word.
"Wish" is usually used in specific expressions, like:
We wish you a Merry Christmas. We wish you a Happy Birthday. Close your eyes, and make a wish. I wish I could come.

Thanks tofor the/your help

We thank someone one for something.

Usually add “a” before singular countable nouns like student.

I want to be an English master because I want to watch "Pirates of the carribean" without subtitle.

Correct spelling and capitalization of the movie title.

So, I write English text on the internet.

Add “the” before internet.

I wish iI watch any movie in English.

Capitalize I

Thanks to you for your help.

This is the standard polite phrase in English.
