Basically you are saying the same thing. I have seen this movie doesn't give you a exact time when you saw the movie. I saw the movie indicates a specific time, although it's not given in the sentence. You could add, I saw this movie in March of last year.
A frequently used and very inccorect usage of the word seen is in its past tense form; Wrong I seen that movie. Correct I saw that movie or I have seen that movie.
They were previewing the movie before it was to be seen by the general public.

Using the word "powerful" in a sentence can be achieved in a number of ways. For example, when describing an emotional movie, one can say that they have seen a powerful movie.
Short answer: tense. Have you seen the movie? - Asking if you've seen the movie as of right now. Had you seen the movie? - Asking if you have seen the movie in the past tense. Think of it in the context of someone asking a question about a story another person told. eg: guy1 - "So I took her to the movie and..." guy2 - "Had you seen the movie before?" guy1 - "Hey idiot don't interrupt." guy2 - "Sorry." guy1 - "Anyways, yeah I had seen the movie twice before..."
Example sentence - We hadn't seen the dog for hours and hoped he would find his way home.

That was the weirdest movie I've ever seen.
I'd rather not answer that question. I'd seen that movie, too.
If you had seen what I just saw, you too might say that you would like to see no more. I've seen a saw like that, too. The second scene of the first act has to be seen to be believed.
No, the word "haven't" is a contraction, a shortened form of the verb (or auxiliary verb) "have" and the adverb"not".A pronoun is a word that takes the place of a noun in a sentence.Examples:I haven't seen that movie. (have not seen)I haven't seen it either. (the pronoun "it" is taking the place of the noun "movie" from the previous sentence)
