After much speculation, we now know why composer Jóhann Jóhannson has parted ways with Denis Villeneuve on his hotly anticipated Blade Runner: 2049, with Hans Zimmer and Benjamin Wallfisch taking over in his stead.

Villeneuve to Al Arabiya English, “The thing I will say is that making movies is a laboratory. It's an artistic process. You cannot plan things. Jóhann Jóhannsson is one of my favorite composers alive today. He's a very strong artist… But the movie needed something different, and I needed to go back to something closer to Vangelis. Jóhan and I decided that I will need to go in another direction — that's what I will say. I hope I have the chance to work with him again because I think he's really a fantastic composer.”

Iceland Review points out that a clause in Jóhannson's contract forbids him from commenting, so we likely will not hear his side of the story any time soon. The composer previously worked with Villeneuve on Prisoners, Sicario, and Arrival.
