Watching an American movie
I've watched all the parts of "Harry Potter" in French, but now that I have become less older (what do you mean here? It's not possible to become younger in age. Do you mean now that I have become older?) I've decided to watch it in English to improve my listening skills. I think that I saw the movie from another angle, so it's quite difficult to understand all the words when I watch American or British movies in native language English.
So I hope to be able to understand all of what I will watch in the future!

Good job! Remember to capitalize I (not i).
