The movie is out on US Netflix. I haven't seen it yet, but from what I've heard so far it's a retelling of stuff that already happened in the series and doesn't exactly match up with the series on some parts of the plot.
I've been waiting for an English version of "The Walls that Lie Between/Separate US" for quite a while as the original is in French and I can't understand enough French to know what the lyrics are. I thought it was a song from the movie, but it's not on the soundtrack.
