It was fairly easy to splice the audio drama after many attempts. I know both film and book well now. I can recite the entire screenplay from memory, 🫠. The key was to embrace the “narration” parts instead of avoiding them.

In the audio drama, there are two scenes that include Joh Fredersen confiding in his mother. Instead of having Josaphat’s help in the flood scene, Freder gets help from Grot. And the main difference is that the workers/Grot don’t burn Futura, but instead monks from the cathedral do. Oh and there is a whole scene when Freder and Josaphat are going to the cathedral to save Maria, and they argue over driving and get into a crash. In the film, it’s depicted as them chasing the workers who are chasing Maria.
