Why is it この映画 and not これ映画?

この is a determiner, which means it must come directly before a noun.

• この映画 = this movie
• これ = this one / this thing

If you wanted to use これ, you would need to say something like これは映画です or just use これ by itself.

を marks the direct object of the verb. In this sentence, the thing being watched is この映画.

So:

• この映画 = this movie
• を = marks it as the object
• 見たいです = want to see/watch

That means この映画を見たいです is literally something like As for this movie, I want to watch it.

What does もう一度 mean?

もう一度 means one more time or again.

It is made of:

• もう = more; again
• 一度 = one time; once
