I don't know French at all. I took some lessons when I was younger but all I know are the numbers. I've been told basically everyone in Monaco speaks English because of it being a huge vacation spot so I'm excited about that. I might not need to learn French after all.
I think once you've finished a movie you really have to detach from it so that you can come back and watch it as an audience member.
