I want to learn British Accent

I want to learn British Accent!! So I try to watch movie, which include lots of actress and actors who speak British. So I will keep trying to repeat after, and learn their accent. The most famous and useful movie for studying British accent is Harrypotter. I want to speak English like Emma Watson. Any way, later, I will go to England to study English. In Engliand, I will not only focus on studying though. I will enjoy traveling, and working and earning my own money! I hope I can be an English teahcer who can speak American English and British English both!
