Fantastic Four: First Steps composer drops two MCU bombshells: there's a second F4 soundtrack we "probably won't ever hear" and he's working on a Werewolf by Night sequel

Fantastic Four First Steps ending.

Fantastic Four: First Steps composer Michael Giacchino revealed he completely rewrote the Marvel film's score after not being happy with the initial soundtrack.

"I actually wrote a whole other score for this film that you probably won’t ever hear. I just remember seeing it for the first time with the music and something didn’t feel right," Giacchino told Deadline.
