If you loved Before the Fall, try The Wave
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Dennis Gansel, and they sit in Drama territory. If that's the register that drew you to Before the Fall, the second film will land in a comparable space — through a different lens.
What The Wave is
A German high school, autumn, a chalkboard scrawled with fascist ideologies. A charismatic teacher lectures, his students apathetic, until an experiment ignites. This cautionary tale lands better with a critical eye on groupthink.
